Dear AFNI experts,

This is my first time using 3dNetCorr. I got an error message but I am not sure how to fix my code. Any help would be much appreciated.

- I want to calculate seed-to-whole brain correlation matrix for resting state data. This is the code that I wrote for one subject:

```
3dNetCorr \
-inset $subj_dir/errts.${subj}.tproject+tlrc \
-in_rois ROI/caudate333+tlrc \
-fish_z \
-ts_wb_corr \
-prefix CORR/${subj}_corr
```

The error message that I got is:

```
Data sets of `-inset' and `in_rois' have different numbers of voxels per brik!
```

- Also eventually I am hoping to get the correlation matrix for each one of four ROIs (the code that I attached here is just for 1 ROI of course), but how do I integrate more than 1 ROIs into my code? The help function says

```
-in_rois INROIS :(req) can input a set of ROIs, each labelled with distinct integers. Multiple subbricks can be input, each will be treated as a separate network.
```

but how do I do this exactly?

Thank you very much in advance!
