Dear all (in particular, Ziad),

for some odd reason using the dot product mode in SUMA stopped working with the latest AFNI.

I get the following message:

++ Notice SUMA_D_Key (SUMA_input.c:1307 @17:26:01):
No contralateral dset
Error SUMA_Set_Sub_String (suma_utils.c:3607):
NULL input
Warning SUMA_AddDsetNodeIndexColAttr:
Failed to set substring for COLMS_LABS at 0
++ Notice SUMA_D_Key (SUMA_input.c:1534 @17:26:01):
Dot product callback active

and SUMA does not compute any dot products. Any ideas what is causing this?

A few notes:

1) This problem occurs with:

Version AFNI_2011_12_21_1014
[[Precompiled binary macosx_10.7_Intel_64: Feb 28 2014]].

but neurodebian, with an older AFNI, is not affected:
Version AFNI_2011_12_21_1014
[[Precompiled binary =Debian-x86_64-1-gnu: Dec 6 2013]]

2) The error message is similar to what was reported earlier:

[afni.nimh.nih.gov]

about which Zaid said "there might be a bug with ConvertDset".

Thanks for your consideration,

best,
Nick
