Hi there FreeSurfer
When trying the GLM-analysis I keep getting the following error. Could you help me with fixing it?
ERROR: matrix is ill-conditioned or badly scaled, condno = 1e+08 -------------------------------- Possible problem with experimental design: Check for duplicate entries and/or lack of range of continuous variables within a class. If you seek help with this problem, make sure to send: 1. Your command line: mri_glmfit --y lh.whiplash.thickness.10B.mgh --fsgd whiplash.fsgd dods --C group_diff.mtx --surf fsaverage lh --cortex --glmdir lh.whiplash.glmdir 2. The FSGD file (if using one) 3. And the design matrix above
Thank you in advance,
Robby

It looks like your fsgd file may have been created on a windows computer. Is that possible? Try reformatting it in linux or mac.

One thing you can try is to run this: cat whiplash.fsgd | sed 's/\r/\n/g' > new.whiplash.fsgd
