[Gat-commits] Error functional analyses: Index exceeds matrix dimensions

[Hannelore Aerts]

Dear GAT experts,

I'm trying to run some graph theoretical analyses on resting-state fMRI data, but in the first step (Network Measures) I already get this error:

please type name of the Data set in single quotation:  'ABIDE'
please type the lowest density of interest (e.g. 0.01):  0.24

Error while evaluating uicontrol Callback

I followed previous suggestions to put first GAT and then spm8 in my path. Also, as input I use "Z.mat" which includes "Z", a 84x84x148 double matrix with input matrices from all subjects, and "names", a 1x84 cell vector with the ROI names.

Does anyone have an idea as how to solve this problem?

Thank you in advance!

Best regards,
Hannelore
