Dear FSL experts,
I'm trying to apply multi-session temporal concatenation to 92 patients and 10 controls using MELODIC. The program has been running for two days and I have obtained a "logs", "inputreg", "groupmelodic.ica" folders. However, the groupmelodic.ica folder only contains "report" folder and log.txt.
In the report_log.html file there appears an error:
"""
An exception has been thrown
Runtime error:- detected by Newmat: process fails to converge
MatrixType = Diag # Rows = 1799; # Cols = 1799; lower BW = 0; upper BW = 0
Trace: Evalue(tql2).
"""
I have used as input data the functional data clean (after filtering the bad components from single-session ICA). Since the input data is clean, I'm not applying any other preprocessing steps (which were already performed with single-session ICA). Then, the main structural images are brain extracted and I'm using 12 DOF and nonlinear registration. The structural images are in the same order of subjects that the input data.
I have also made sure that all the input data contain the same number of volumes because I believe that it will crash otherwise. But the problem is that it crashes and I don't know why. Could someone please help me or give me a hint of what the problem might be or how to search for it on the files obtained? I would really appreciate it.
Thank you very much for your help in advance,
Laura
