Questions of GISTIC and copy number alteration analysis

[xiw588]

Describe the issue
Hi I am planning to analyze copy number alterations in a small cohort (n=15), and I have the segmentation data in TCGA format. I tried to generate GISTIC files for maftools, however it failed due to limited sample size. I wonder if you have any suggestions to get this around. Thanks
