Hello,

Thank you for the great toolbox.

We are currently trying to run a dynamic FC ROI-to-ROI analysis using conn17a. We are simply trying to get a hang of the feature, thus we are doing a test run with data from only two subjects.

The initial steps of the analysis seem to work to completion with our ROIs and subject data: denoising comes to completion, then in 'first level analyses' I click 'done' to run the dynamic FC analysis, and immediately I receive the following error:


"Error using eig
Input to EIG must not contain NaN or Inf.
Error in conn_ica (line 47)
[Q,D]=eig(X*X'/(Ns-1));
Error in conn_invPPI (line 174)
[S,W]=conn_ica(reshape(B1,[Nr*Nr Nk1])',[],'dodisp',DOPLOT,'rndseed',RNDSEED);
Error in conn_process (line 3075)

I see that similar issues have been brought up and addressed for previous versions of the toolbox, but unfortunately I was not able to find a solution that worked for me.

I look forward to your response.

Thank you,
