Permutation --perm-resid unrecognized
by Avi Gharehgazlou 09 Jun '20

09 Jun '20

External Email - Use Caution Hi experts, I am trying to run permutation test on my lGI data using the command line below but I get an error saying “ERROR: Flag --perm-resid unrecognized”. I've ran my mri_glmfit command line with flag --eres-save (see below) and have installed and made executable the new version of mri_glmfit-sim as instructed here: ( https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/MultipleComparisonsV6.… ) Will you please tell me how I can fix this? permutation command line I used: mri_glmfit-sim --glmdir lh.lgi.TD_PTSD_age_SA_IQ_FWHM0.glmdir --perm 1000 4.0 abs --perm-resid --cwp 0.05 --2spaces --bg 1 mri_glmfit command line I used: mri_glmfit --y lh.lgi.TD_PTSD_age_SA_IQ_FWHM0.mgh --fsgd fsgd.txt dods --glmdir lh.lgi.TD_PTSD_age_SA_IQ_FWHM0.glmdir --surf fsaverage lh --C group.diff.mtx --C group-x-age.mtx --C group-x-SA.mtx --C group-x-IQ.mtx --C lgi.intercept.mtx --C maineffect.age.mtx --C maineffect.IQ.mtx --cortex --eres-save Also, is it okay to run the --eres-save flag with mri_glmfit regardless even if I decide to do another correction (i.e. monte carlo later later on) or would results get affected? Thank you so much for your support, Avi

gtmseg getSignalBehindHead ERROR (no slices behind head)
by Boris Rauchmann 08 Jun '20

08 Jun '20

External Email - Use Caution Dear FS experts, In my dataset I have 4 subjects where the T1 was acquired, planning the FOV very close to the occipital lobe. I guess that triggers the error: getSignalBehindHead ERROR (no slices behind head) WARNING: only 0 < 7 slices behind head! ERROR: xcerebralseg and results in gtmseg exited with errors. How can I fix this? Best regards, Boris
