Hello,

Signs of Z scores I am getting when running VLSM analysis in NiiStat and MRIcron NPM are reversed. Areas of significance are almost identical but the Z scores are positive in MRIcron NPM and negative in NiiStat. I have used the same design/parameters and behavioural scores in both cases. The documentation of NiiStat and MRIcron would indicate behavioural scores are interpreted the same in both packages (higher scores mean better performance) and therefore I would expect the sign of Z scores in both packages to coincide.

Could you please provide clarification on this issue?

I thank you in advance for your help.

Best,

Juan
