Dear all,

I meet an error while the ISC analysis is finished and launching the GUI

When the analysis is finished, the error is:

ans =

'30-Sep-2021 16:42:28'
ans =
'30-Sep-2021 16:42:28'

In addition, when Calculating permutation distributions for each ISC map, the feedback looks weird too.

When I try to launch the GUI, there's a warning "Unexpected error while opening visu-GUI with the current parameters, use File->Open to find a correct parameter-file.

In the beginning, I thought there might have some subjects make the problem, so I try to do the same analysis with fewer subjects several times. Unfortunately, if I just include 5-6 subjects in the analysis, no one will make the error. Does anyone know how to deal with this problem?

Thanks.
