VMHC computing error and functional connectivity / ReHo results

Dear Experts,

I have two questions. The first one is regarding the results of functional connectivity analysis and ReHo.

I calculated the fc matrix between the DMN nodes using the provided atlas which resulted in 2 sets of results in the ROISignals_FunImgARCWSF  directory. One is FisherZ the other is plain ROICorrelation matrix. I'd like to feed the results to SPSS to use in statistical evaluations including other variables. Which one should I use, I guess FischerZ would mean Z-scores, but I do not know where those z values are calculated from, so I can not decide which one to use. The same goes to the reho maps where I have plain reho maps, mreho maps and z rehomaps and don't know what those maps represent.

The other issue is an error that I get if I try to calculate VMHC.  I'm using Matlab 2019b under linux mint with spm12 and DPARFS A . 

The error is the following:
