Dear Experts,
I am new to FS. I'm trying to run mri_glm fit
I've created FSGD with 2 classes -responders vs non-responders to a given intervention- and 3 variables to be regressed out-according age, gender, laterality.
I've made my FSGD file is made in accordance with documented FS directions. I've created the contrast vector in accordance to Nregressors and it works out to be
1 -1 0 0 0 0 0 0
I add I'm using DODS to do this task.
the constructed command I used is this mri_glmfit --y lh_test.smoothed10FWHM.mgh --fsgd newCH.fsgd dods--C groupdiff.mtx --surf fsaverage lh--cortex --glmdir lh.test.glmdir
1) The first problem encountered is INFO: DeMeanFlag keyword not found, DeMeaning will NOT be done
I have tried to demean my data adding the flag --demean, which I found in more than one forum, but i think this is an incorrect flag as it didnt work anyway.
2) I have constructed my contrast vector also in accordance with FS directions, in a text editor adding the extension .mtx I'm getting this error
ERROR: gd2mtx method dods--C unrecoginzied. Legal values are dods, doss, and none.
Help would be much appreciated.
