Dear FSLers,
after calling melodic (group ICA, N=160, each 177 time points) with a shell command I get an error right after the PCA starts that reads:
Data size : 3040 x 50801
Starting PCA ...
An exception has been thrown
Logic error:- detected by Newmat: element error: requested index (wrt 0) = 3040
MatrixType = Diag # Rows = 3040; # Cols = 3040; lower BW = 0; upper BW = 0
Trace: Evalue(tql2).
The program then stops.
A totally unrelated analysis could be successfully finished though the Data size of the matrix for PCA was even larger:
Data size : 5670 x 56312
Starting PCA ... done
[successfully finished after that]
Does anyone have an idea what might go wrong here? The 4D-data files look okay, have the same size; the mask is correct, the call of melodic itself seems correct. The swap space of the machine is quite large.
Thanks a lot for any hints to solve this problem!
Philipp
