Hi,

this error was reported several times in the marsbar forum. Matthew Brett suggested to use K. Worsleys fmristat instead of the autocorrelation implementation in SPM. For that you must insert the following code in the file basco_checkestimation on line 16.

D = autocorr(D, 'fmristat', 2);

I have also noticed that sometimes I get the error "Check number of ROIs in txt-file"
I changed line 225 in BASCO.m from
if length(thenames)~=ROINum
to
if size(thenames,1)~=ROINum

and it worked.

Best
Ralf
