Hello all,
I’ve just finished retinotopy analysis following
http://surfer.nmr.mgh.harvard.edu/fswiki/FsFastIndividualRetinotopyAnalysis….
Now I’m wondering, is it possible to get quantitative values of polar angle and
eccentricity for each vertex from, say, an ROI I’ve drawn out? If so, how wou
Hi,
Thanks a lot.
I corrected the files as you suggested and now it finished without error.
Best,

Thank you once again!
Yes, that is true.
The bval and bvec file were doubled, so I removed half the values (and also the
empty spaces) and the fMRIframe: frame >= nframes stopped from happening.
A converted the dcm to nii using dcm2nii software, and used its bval and bvec
files as input to TRAC
Hello freesurferers,
I ran this command (3 is my subject name):
selxavg3-sess -a Retinotopy.3.lh -s 3
and got this error message:

If the b-value table has 130 entries, then the gradient table should have
130*3 entries (one x,y,z direction vector for each b-value). This error
means that there are fewer entries in the gradient table than there should
be. Run wc -w on
The error message is "data and bvals/bvecs do not contain the same number
of entries". This doesn't necessarily mean that the bvecs and bvals don't
agree with each other, but that the bvecs and bvals don't agree with the
DWI data.
Based on this line in the log file, there are 130 frames in t
