[Freesurfer] Multiple Comparisons Correction thresh error

Hello, I would like to correct my glm_fit results for multiple comparisons. I am using the following commands, similar to the one in the group analysis tutorial: mri_glmfit-sim  --glmdir lh.index.glmdir  --cache 1.3 abs  --cwp 0.05  --2spacesmri_glmfit-sim  --glmdir lh.index.glmdir  --cache 2.0 pos  --cwp 0.05  --2spaces And receive the following errors: ERROR:thresh=1,3, must be 1.3, 2.0, 2.3, 3.0, 3.3, 4.0 ERROR:thresh=2,0, must be 1.3, 2.0, 2.3, 3.0, 3.3, 4.0 I am sure I am typing a point, but it is read as a comma. Any ideas why? Freesurfer version: freesurfer-Linux-centos6_x86_64-stable-pub-v5.3.0 Platform: Ubuntu MATE 16.04 Thank you very much! Regards,Teodora
