Hi all,
I have some multi-echo resting state data that I've preprocessed using ME-ICA (part of AFNI). I'm looking to manually remove components using fsl_regfilt. The time series for all ICA components is in an output file 'meica_mix.1D', which I have attempted to use as the mixing matrix containing the time courses (-d). The input file contains component maps (in units of \delta S) of all ICA components. However, I get the following error: 'libc++abi.dylib: terminating with uncaught exception of type NEWMAT::IncompatibleDimensionsException'.
I did remove the extension (1D) for meica_mix.1D, and converted this file into the same format as accepted by fsl_regfilt, but I continue to get the same error. It might be a long shot, but I was wondering if anyone had any suggestions or fixes for this, or if it is likely just not possible to use fsl_regfilt on ME-ICA outputs.
Many thanks,
Sara
