Hi :
I searched through the archive and didn't find a solution to this problem: Running group melodic (concatenated mode)
on 68 subjects. I set 75 components. Input to group melodic are filtered_fun_data_clean (that is, we use the output of running fix with a threshold of 5, so about 20-30% of components got removed form initial individual melodic).
It gets stuck at this point:
.........../reg_standard/filtered_func_data ... done
Removing mean image ... done
Individual whitening in a 75 dimensional subspace
Data size : 5100 x 30655
Starting PCA ...
An exception has been thrown
Runtime error:- detected by Newmat: process fails to converge
MatrixType = Diag # Rows = 5100; # Cols = 5100; lower BW = 0; upper BW = 0
Trace: Evalue(tql2).
Thanks so much for your help!
Lino
