Dear all,
When I was to process the GLM with tCCA, the Homer system reported the following error message.
Can anyone help me solve this problem?
Error message as follows:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
errmsg =
0×0 empty char array
Processing iGroup=1, iSubj=1, iRun=2
Warning: Matrix is close to singular or badly scaled. Results may be inaccurate. RCOND = 2.897067e-17.

The error message says that you have no auxilliary or short separation measurements to use in the filter. You should watch this lecture from 2021 on doing GLM with tCCA and do the exercise as well. See here.
