Hi all, I try to run mri_glmfit, but it export "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.". I upload the data in the attachment, and the glmfit_output is the standard output of the "mri_glmfit". Thanks. All the best. 2013-12-19
