Hi all, I'm working on a group analysis using mri_glmfit. In analysis directory, I got a X.mat file which containing the matrix X ( size 50x4 ) used to regress analysis, also the beta value from beta.mgh file. Strangely, I loaded the X.mat in Matlab and recalculated the beta using function regress in matlab, but got a different result from that of mri_glmfit. I don't know where the problem is, is there any difference in algorithm between mri_glmfit and matlab function regress( regress(Y,X) )? or I made some mistakes during the procedure. The X.mat file and the dependent variable Y.mat are in the attachment.
Thanks in advance Lijie Huang
