Don't try and load modules

[gdevenyi]

You're trying to run commands that don't exist on standalone systems, or loading modules which don't exist on HPCs under the same name:

QSMART/QSMART_toolbox_v1.0/brainmask.m

Lines 10 to 14 in e51526d

	%%bias field correction
	unix('module load ants/1.9.v4; N4BiasFieldCorrection -i mag1_sos.nii -o mag1_sos_n4.nii');
	%%mask
	%(1) brain mask
	unix('module load fsl/5.0.9; bet2 mag1_sos_n4.nii BET -f 0.2 -m');

Please assume that the user has managed to setup their environment properly.

Thanks for identifying this issue, I'll update the code to ensure that the code can run on environments other than the one that we used.
