Dear FS experts

We run mri_glmfit and encountered the following error:

INFO: gd2mtx_method is doss

Saving design matrix to LTHV_Thickness_LH_correlation_memory2.glmdir/Xg.dat

Normalized matrix condition is 1e+08

Design matrix ------------------

--------------------------------

ERROR: matrix is ill-conditioned or badly scaled, condno = 1e+08

The command line is as follow:

mri_glmfit --y LTHV_lh_thickness.15.mgh --fsgd LTHV_fsgd_correlation_memory2.txt doss --glmdir LTHV_Thickness_LH_correlation_memory2.glmdir --surf average_LTHV_TP1 lh --C LTHV_Design_corr.mat —cortex

The FSGD and Design files are attached

We did not find the problem.

Thanks in advance for your help.

Regards

Jürgen Hänggi
