Hi Afni experts,

I'm having some troubles trying to extract the time series from some surface-based regions I created with freesurfer. I did the following steps:

1. I drew some regions on the individual surfaces with Freesurfer (labels)
2. I created an annot file with mris_label2annot
3. I used FSread_annot to convert the annot file to the .roi file
4. I turned the roi into a dataset with ROI2dataset

Now I'm trtying to use ConvertDset to assign a value to each vertex of the region/mask but I got the following error message.

ConvertDset -i lh.V1dorsalDM.1D.dset -o_1D -pad_to_node ld120 -prefix lh.V1dorsalDM.FULL

d120 -prefix lh.V1dorsalDM.FULL
++ Notice ConvertDset (SUMA_ConvertDset.c:881 @13:56:22):
Padding output dset until node 144001
Error SUMA_PaddedCopyofDset (suma_datasets.c:3656):

Thanks in advance,
