Thanks for your feedback. I tried running 3dNetCorr with these parameters :

3dNetCorr \
-inset pc09.p64_rest_run1_MEICA.spc.nii.gz \
-in_rois test_resamp_addtROI_2func+tlrc. test_resamp_audcatROI_2func+tlrc. \
-fish_z -ts_wb_corr -mask p64_rest_run1.REF.mask.FBrain.MNI.nii.gz \
-prefix test_p64_netcorr

and I got this error:
++ Reading in.
++ Allocating...
++ User didn't enter mask: will make my own, based on where I find nonzero time series.
++ Applying mask to ROIs.
++ Labelling regions internally.
++ No refset labeltable for naming things.
++ Getting volumes.
++ Calculating average time series.
++ Calculating correlation matrix.
++ Writing output: NETCORR ...
