Exchanagability blocks in fixelcfestats

Hi, I’m trying to run fixelcfestats on HCP data and specify permutations according to family structure using the palm_quickperms function to generate a file that can be fed into the fixelcfestats command under the -permutations flag. I saw someone doing this in Exchangability blocks for nbse connectomestats, and I’m following the procedure outlined in https://fsl.fmrib.ox.ac.uk/fsl/fslwiki/PALM/ExchangeabilityBlocks under the “Generating the set of permutations only” heading. However, though I specify an exchangeability blocks file meant to create many permutations, the script only produces one permutation. Has anyone else run into a similar issue?

My code is as follows:
[Permutations, VG] = palm_quickperms([], ‘EB1031.csv’);
dlmwrite(‘permutations_file.txt’, Permutations)

With EB1031 being the exchangability blocks file.

Hi Katherine,

I’m pretty sure the palm_quickperms() function will expect its inputs to be data already imported in Matlab / Octave, rather than strings corresponding to files.
