Example of results of Grouped Analysis for a school case

Make the grouped analysis:

1- Make the Configuration Parameter file:

We will do the data merge, normalization (unless individual normalizations are kept), dimension reduction, and evaluate the biais and the clustering. Alignment, quality control and filtering have already been done in the individual sample analyzes (see Example of results of Individual Analysis for a school case for more information). To simplify the explanation, we will keep the normalizations by SCTransform to allow the comparison with the integration by Seurat, but we could test other methods. I advise to save if you keep the individual normalizations (or not) in the name you give to the grouped object (here: name.grp : ["sc5p_v2_hs_PBMC_Grp_keep"]).

1- Launch of the analysis:

For the traceability of the analysis, I prefer to put the command lines in a script, but it is not mandatory.

1- Interpretation of results:

The Grp_Norm_DimRed_Eval_GE step corresponds to the Norm_DimRed_Eval_GE step but with a data merge step beforehand. The results, their interpretations, and their conclusions, are similar to those described in the Norm_DimRed_Eval_GE section of the individual sample analysis. Thus, I would develop the analysis succinctly. For more details, please refer to the section Normalization, Dimension Reduction, Biases and Clustering Evaluation of Individual analysis.

Merge, Normalization and Dimension Reduction:

Correlation graph:

This graph represent the correlation between potential biases and each dimension, after nomalization and dimension reduction. Here, we choose to keep the individual normalizations (to compare this results with the results of the integration) so we can't correct biases (we will be able to estimate the impact of the biases on the final umap results). There appears to be a correlation between the levels of RNA encoding ribosomal proteins, the levels of stress RNA and the number of transcripts, with the dimensions.

As usual, to identify the number of dimensions to keep for clustering as well as the adequate resolution, the pipeline has drawn all possible umaps according to these 2 parameters. We have to look at all the umaps and choose the one that seems to be the most "beautiful": cluster well isolated from each other, cells well grouped within its cluster. As in the integrated analysis, we know ​​the expected number of clusters because we performed the individual analysis of each sample, so we know the cell types (or cell subtypes) present.

Clustree plots:

The clutree plot is a tree plot to observe the influence of a parameter on the results. Here we measure the evolution of the membership of cells to a cluster:

  • the resolution is fixed and the number of dimensions to keep evolves:

The goal is that the membership of the cells in a cluster remains relatively stable.

Here, the umap are very stable across different dimensions (like in integrated analysis). I choose 25 dimensions and a resolution of 0.4. The clusters seem more grouped together and contaminate each other less. Like in integrated analysis we have 13 clusters, very close to integrated results so the interpretation is the similar. (I have tested up to 100 dimensions but the cell subtypes are not visible too.)

2- Make the Configuration Parameter file:

We will do the clustering, find the marker genes, make the annotation, add ADT, add TCR, add BCR and convert main results into a cerebro object. We keep the same Configuration Parameter file, but we add Grp_Clust_Markers_Annot_GE, Grp_Adding_ADT, Grp_Adding_TCR, Grp_Adding_BCR and Cerebro steps. Some parameters (as name.grp and input.rda.grp) will be determined automatically thanks to the Grp_Norm_DimRed_Eval_GE step.

These graphs correspond to the 2D and 3D umaps of the data with the assignment of cells to their cluster. It corresponds to the umap chosen in the previous step.

These graphs correspond to the umap of the data with the assignment of cells to their sample (concatenated view, and splited view).

We observe that the cells of the 2 samples are NOT present in all the clusters. There is a batch effect! The cluster 7 only belongs to sample sc5p_v2_hs_PBMC_1k_5gex_GE, and the clusters 1 and 3 only belong to sample sc5p_v2_hs_PBMC_10k_5gex_GE.

Final umap with biases:

Provided by the Grp_Clust_Markers_Annot_GE step.

/mnt/beegfs/userdata/m_aglave/pipeline/single-cell/examples/complete_grouped_integrated_analysis_example_of_wiki/Results/GROUPED_ANALYSIS/NO_INTEGRATED/sc5p_v2_hs_PBMC_Grp_keep/NORMKEPT/pca/dims25_res0.4/technical/sc5p_v2_hs_PBMC_Grp_keep_technical_MULTI_ALL_uMAPs.png

This group of graphs corresponds to the plotting of biases on the umap. The goal of these graphs is to check the correction or not of biases. The cells should not be separated according to biases, but according to the biological processes of interest of the cells.

The interpretation is similar to that of the Clust_Markers_Annot_GE step. Here, there does not seem to be any influence of mitochondrial RNAs, nor of the cell cycle. We can observe a potential effect of the RNAs which code for ribosomal proteins, but we can't correct this effect because we kept the individual normalizations (and remember: the correction of this bias depends on the studied biological process). Also, we can observe a cell of cluster 12 which appears to be highly stressed (like in integrated results).

As in Clust_Markers_Annot_GE step, here you can see the number of marker genes specific to a cluster and the number of marker genes shared between several clusters (the first graph matches all the results and the second graphs matches the 10 marker genes with the highest logFC for each cluster).

  • adj.P.Val > 5%,
  • avg_log2FC > 0,5 (positif log2FC only),
  • pct.1 or pct.2 > 0,75 (pct.x: percentage of cells in the group x expressing the tested gene (example: 0,75 corresponds to 75% of cells); min.pct: threshold used for pct.1 and pct.2).

The heatmap represents the expression of the 10 best marker genes in logFC for each cluster for all cells group by cluster. The expressions were normalized between the genes in order to allow a visual comparison between these genes. See Clust_Markers_Annot_GE for more details.

Here, we observe that clusters 1, 2,3 and 7 are similar, even if they have a few genes with different expression,so maybe they are the same cell type (thanks to the integration analysis, we know that these cells are T Lymphocytes).

The violinplot represents the expression of the 10 best marker genes in logFC for each cluster by cell for all clusters. The expression of the marker gene of each cell is plotted by cluster. This allows to verify that a marker gene is quite specific for a cluster and is not shared by other clusters.

For example, the LYZ gene is a marker gene of cluster 0 but it's also highly expressed in cluster 9. So it isn't specific of this cluster. The S100A12 gene is a marker gene of cluster 0 and it's lowly expressed by other clusters, so it is very specific of this cluster.

Markers plot from the Markfile:

Provided by the Grp_Clust_Markers_Annot_GE step.

This is a representation of all genes from the Markfile. It can help to annotate cell types.

Annotations:

Provided by the Grp_Clust_Markers_Annot_GE step.

The automatic annotation is done with clusterifyR and singleR as in Clust_Markers_Annot_GE step.

Here, I present you 2 examples (one realized on the clusters, the other realized on each cell). These are the same examples as for the integrated analysis. Warning: the references provided with the tools are not necessarily very relevant (from microarray or bulk RNA-seq) but they are the best available at the moment. So, the results should be interpreted with caution.

Note:
It is better to group the information to annotate the cells: the automatic annotation, the marker genes and the Markfile genes.

By cross-checking the results with the Markfile we can conclude that:

  • cluster 0 corresponds to Monocytes,
  • cluster 1 corresponds to Lymphocytes T CD4+,
  • cluster 2 corresponds to Lymphocytes T CD4+,
  • cluster 3 corresponds to Lymphocytes T CD8+,
  • cluster 4 corresponds to Lymphocytes B,
  • cluster 5 corresponds to Lymphocytes T CD8+,
  • cluster 6 corresponds to NK cells,
  • cluster 7 corresponds to Lymphocytes T (CD4+?, CD8+?)
  • cluster 8 corresponds to Monocytes,
  • cluster 9 corresponds to Dendritic cells,
  • cluster 10 corresponds to Lymphocytes T CD4+?
  • cluster 11 corresponds to Dendritic cells,
  • cluster 12 corresponds to Megakaryocytes? Platelet cells?

So, if we compare to the integrated analysis:

grouped integrated
cluster 0 <=> clusters 1 and 2
cluster 1 <=> cluster 0
cluster 2 <=> cluster 3
cluster 3 <=> cluster 4
cluster 4 <=> cluster 5
cluster 5 <=> cluster 6
cluster 6 <=> cluster 7
cluster 7 <=> cluster 6 ?
cluster 8 <=> cluster 9
cluster 9 <=> cluster 8
cluster 10 <=> cluster 10
cluster 11 <=> cluster 11
cluster 12 <=> cluster 12

ADT:

Comparison gene expression and protein level plot:

Provided by the Grp_Adding_ADT step.

This plot shows the normalized expression of the genes (left) with the normalized expression of the corresponding proteins (right). Often protein expression is very strong with background noise due to non-specific hybridization of the antibodies. To solve this problem we can modify the cutoff of the legend by quantiles.

/mnt/beegfs/userdata/m_aglave/pipeline/single-cell/examples/complete_grouped_integrated_analysis_example_of_wiki/Results/GROUPED_ANALYSIS/NO_INTEGRATED/sc5p_v2_hs_PBMC_Grp_keep/NORMKEPT/pca/dims25_res0.4/ADT_results/ADT_dimplot_legend_cutoff.png

This plot shows exactly the same things, but with a legend cutoff (default parameters).

TCR:

Provided by the Adding_TCR step.

There are several ways to define a clonotype:

  • gene: use the genes comprising the TCR.
  • nt: use the nucleotide sequence of the CDR3 region.
  • aa: use the amino acid sequence of the CDR3 region.
  • gene+nt: use the genes comprising the TCR + the nucleotide sequence of the CDR3 region for T cells. This is the proper definition of clonotype.

Global analysis:

Note:
All the TCR and BCR results, are the same between integrated and grouped analysis; only umap and the analysis by clusters are differents.

Unique Contigs Quantification:
/mnt/beegfs/userdata/m_aglave/pipeline/single-cell/examples/complete_grouped_integrated_analysis_example_of_wiki/Results/GROUPED_ANALYSIS/NO_INTEGRATED/sc5p_v2_hs_PBMC_Grp_keep/NORMKEPT/pca/dims25_res0.4/TCR_results/Global_analysis/quantUniqueContig.png

This group of graphs represents the number of different (unique) clonotypes in the sample.

Here, we can observe that almost all contigs are present in a single copy (they are unique), regardless of the definition of clonotypes chosen. For clonotypes defined only by their gene, we observe 444 unique contigs out of a total of 451 contigs for sc5p_v2_hs_PBMC_1k_5gex_GE and 4112 unique contigs out of a total of 4443 contigs for sc5p_v2_hs_PBMC_10k_5gex_GE.

Clonotypes Abundance:
/mnt/beegfs/userdata/m_aglave/pipeline/single-cell/examples/complete_grouped_integrated_analysis_example_of_wiki/Results/GROUPED_ANALYSIS/NO_INTEGRATED/sc5p_v2_hs_PBMC_Grp_keep/NORMKEPT/pca/dims25_res0.4/TCR_results/Global_analysis/abundanceContig.png

This group of line graphs represents the number of clonotypes depending on the number of cells where the contig is present. The points of the graph are connected.

The interpretation is the same as for the TCR part of the individual analysis of samples, but we have the 2 samples present on the graphs.

Here we have mostly single clonotypes, present in a single cell, which is represented by a dot at over 400 clonotypes with an abundance of 1 for sc5p_v2_hs_PBMC_1k_5gex_GE sample and at over 4000 clonotypes with an abundance of 1 for sc5p_v2_hs_PBMC_10k_5gex_GE sample. It is in agreement with the previous graph of unique contigs.

Clonal Space Homeostasis:
/mnt/beegfs/userdata/m_aglave/pipeline/single-cell/examples/complete_grouped_integrated_analysis_example_of_wiki/Results/GROUPED_ANALYSIS/NO_INTEGRATED/sc5p_v2_hs_PBMC_Grp_keep/NORMKEPT/pca/dims25_res0.4/TCR_results/Global_analysis/clhomeo.png

By examining the clonal space, we are effectively looking at the relative space occupied by clones at specific proportions. Another way to think about this would be thinking of the total immune receptor sequencing run as a measuring cup. In this cup, we will fill liquids of different viscosity - or different number of clonal proportions. Clonal space homeostasis is asking what percentage of the cup is filled by clones in distinct proportions (or liquids of different viscosity, to extend the analogy).

The interpretation is the same as for the TCR part of the individual analysis of samples, but we have the 2 samples present on the graphs.

Clonal Proportion:
/mnt/beegfs/userdata/m_aglave/pipeline/single-cell/examples/complete_grouped_integrated_analysis_example_of_wiki/Results/GROUPED_ANALYSIS/NO_INTEGRATED/sc5p_v2_hs_PBMC_Grp_keep/NORMKEPT/pca/dims25_res0.4/TCR_results/Global_analysis/clprop.png

Like clonal space homeostasis above, clonal proportion acts to place clones into separate bins. The key difference is instead of looking at the relative proportion of the clone to the total, the clonalProportion() function will rank the clones by total number and place them into bins. Example: [1:10] are the top 10 clonotypes in each sample.

The interpretation is the same as for the TCR part of the individual analysis of samples, but we have the 2 samples present on the graphs.

The frequency represents the number of cells that contain the clonotype based on its amino acid sequence. We have theses results for each sample and the integration.

Here, we can confirm the observations of the individual analysis of each sample. The localization of clonotypes on the umap confirms the T cell annotation of the clusters. We also observe that not all T cells have an identified TCR.

This group of graphs are similar to that of the globale analysis, but by clusters, and for each sample and the merger, so the interpretation is similar too.

The graph represents the percentages of common clonotypes between 2 clusters (scaled to the number of unique clonotypes in the smaller cluster). The tables which present the number and the sequence of common clonotypes between the clusters are not shown here but are computed too.

The interpretation is exactly the same as individual analysisof sample.

BCR:

Provided by the Adding_BCR step.

The results provided for the BCRs are the same as for the TCR analysis. So I will not explain again. We observe that all the clonotypes are unique except 3 (1 in sc5p_v2_hs_PBMC_1k_5gex and 2 in sc5p_v2_hs_PBMC_10k_5gex, and isn't the same clonotype). In addition, the clonotypes colocalize well with the cluster of B lymphocytes identified with the annotation. Cluster analysis is not very interesting because we have only one cluster of B lymphocytes in this example. There are one clonotype in cluster 0, but it is probably an artefact.

Cerebro:

Provided by the Cerebro step.

Cerebro file can be loaded into CerebroApp R Shiny to exploit the main results.

Notes:

  • The cerebro file is not present in the results because its size exceed the threshold of 50 mb of github to store it.
