Minimal test data for continuous integration testing - minc 1 and nifti formats.

dev-0.14.0

Fixes and Features

• Separate brick for generation and regression of confounds. The fMRI data is now saved right after resampling, along with confounds. This means it is very fast to reprocess the data using different options for confound regression. It will also be easy to re-use data outside of NIAK, e.g. in FSL or SPM.
• scrubbing is now done on windows of a given width, in seconds, by default 1 sec (or 1 TR, whichever comes first) before and 6 seconds ( or 1 TR at minimum) after. Before, the window was defined in termes of time points, which did not scale with TR.
• scrubbing is now saved in a mask in the extra.mat file. Scrubbed points are left in the 4D volumes, but ignored in the regression of confounds (although the regression is still applied to them, the weights of the regression are estimated without them). All pipelines (region growing, basc, basc-fir, connectome, scores, glm-connectome), have been modified to discard the scrubbed time points.

BOSS v0.13.5

Fixes and Features

• New algorithm for BOLD/T1 MRI coregistration. The T1 brain mask is now edited to (1) add extra-CSF located around the meninges in the mask. These spaces take up contrast in BOLD images and need to be included for proper registration; (2) remove ventral portions of the frontal cortex and temporal poles. Those are typically impacted by signal loss in BOLD images. The amount of signal loss can be tweaked by a parameter.
• New data in niak_wget (see this commit)
• Bug fix in the selection of alternative slice timing interpolation schemes (see this commit).
• Fix the region growing grabber (see this commit).
