Hi, I have my own stats files that I would like to incorporate into the freesurfer stream, if possible. Ie. after running FreeSurfer, I create a ?h.mystats (containing something like image intensities for example), where the format of ?h.mystats is just an ascii file, where each line is the value at that vertex.
What I ultimately want to do, is to transform ?h.mystats into fsaverage space, that way I can compare ?h.mystats across subjects. I was hoping I could use the given sphere.reg which has already been calculated to do this.
I renamed ?h.mystats to ?h.thickness and tried the following which I think will work: mris_preproc --s mysubject --hemi lh --meas thickness --target fsaverage --out lh.thickness.fsaverage.mgh
But it complains that:
Reading curvature file /lab1/FreeSurfer/4.0.5/ms-mni/testing//tester/surf/lh.thickness MRISreadBinaryCurvature: incompatible vertex number in file /lab1/FreeSurfer/4.0.5/ms-mni/testing//tester/surf/lh.thickness
I checked and I have the same number of lines in my file as vertices on my object so my questions are:
1. Do I have to convert my ascii ?h.mystats to a curvature (binary) file like ?h.thickness, and if so how does one do this? 2. Is this the right way to get what I ultimately want to do, or is there another method?
thanks, mishkin
