Issue with running deface on NIFTI images

[nshreyasvi]

Hello,
I was trying to run mri_deface after running DICOM to NIFTY converter. For the output of DICOM 2 NIFTY converter, I am used the argument -z y which generates a .nii.gz file as an output. However, when I try to run mri_deface over the .nii.gz files, I am getting the error GCAalloc: could not allocate nodes Cannot allocate memory
My commands.json file looks as follows:

I would like to know what would be the cause of the error and how could I fix it?
