Hi
I am doing network analysis by using gretna. I've already got functional connectivity matrix which has been converted by using Fisher's z-transformation. 

When I tried to do the network and nodual network analysis by using gretna, I got 

'''
Something went bad ... the job has FAILED !
The last error message occured was :
Error using logical
NaN's cannot be converted to logicals.
'''


Is it because the matrix was converted by using Fisher's z-transformation? Should I use the functional connectivity matrix without Fisher's z-transformation?




I really appreciate if you can help us with my problem.

Thanks in advance
