Hi Freesurfer experts,
I'm trying to analyze some phase-encoded data with the eccentricity protocol for retinotopic data and I'm having troubles with selxavg3-sess.
I run the following commands:
mkanalysis-sess -analysis OrderDisorder.idsubj.lh -surface idsubj lh -TR 2 -retinotopy 24 -paradigm rtopy.par -fwhm 0 -per-run -nskip 5 -fsd bold
selxavg3-sess -a OrderDisorder.idsubj.lh -s idsubj_OrderDisorder_continous
and I got this error message:
Found 122573/130829 (93.7) voxels in mask Creating Design Matrix ... creation time = 0.019 sec DoMCFit = 1 ntptot = 875, nX = 80, DOF = 795 Saving X matrix to /usr/local/freesurfer/fsfast/OrderDisorder_new/MK_OrderDisorder_continous/bold/OrderDisorder.MishaK.lh/Xtmp.mat Error using svd Input to SVD must not contain NaN or Inf.
Error in cond (line 35) s = svd(A);
Error in fast_selxavg3 (line 279) XCond = cond(XtX);
I attached the Xtmp.mat file from the output folder in case is needed.
Thank you! Best Francesca
