Hello-
I'm trying to run randomise and keep getting a segmentation fault. It's probably something obvious and apologies if it is.
I'm using fsl 5.0.10, Linux.
My input file is 256 x 256 x 252 x 41
I created the 4D file in the same order that my mat/con files are in and have verified that the number of entries and number of subs match. For the mat file, NumPoints is listed as 41. My template mask matches the x/y/z dimensions of the input 4D file. My groups and covariates look fine, my contrasts are just G1 > G2, G2 > G1.
My randomise command is the following:
randomise -i group4D -o twoSampT -d design.mat -t design.con -m groupTemplate_mask.nii.gz -T -D -n 5000 -x --twopass
#I've tried this with and without the "-x" option and get the same error.
I've run the command in the directory where all of the data lives, I've also tried setting paths, both with the same error. Every time I've run this, it fails at exactly permutation 742. It doesn't matter with machine I use, or which version of fsl (I even tried this on 5.0.2.2). I have a system monitor up and can verify that RAM never goes above ~8 GB (of 16).
I've tried searching prior JISCMail threads but I only found two relevant posts, one pointing a time dimension larger than x/y/z and another pointing to a missing flag/argument. It's definitely not the former but possibly the latter? What am I missing in my command or what shouldn't be there? Many thanks in advance.
