Dear AFNI experts,

After converting a statistical output file from orig to tlrc with @auto_tlrc, when attempting to use 3drefit -atstring to link the results of 3dClustSim to the tlrc statistical file, I found the following error message:

Warp already there!Error: Failed to create WarpData!

The same error message does not appear when link the ClustSim tables to the orig statistical file. However, I've also found that if I apply 3drefit -addFDR to the tlrc statistical file before applying 3drefit -atrstring, such error message did not appear. So I wonder the following:

1) Is it right that @auto_tlrc carry the -addFDR and -atrstring information on the orig file to the tlrc file? This seems reasonable to be because after the transformation the shape, size, and spatial resolution change, and the original ClustSim tables associated with the orig file do not fit the tlrc file.

2) What is the meaning of the "Warp already there..." error message? Why does it appear, and why doesn't it appear if 3drefit -addFDR was applied first?

The script and the data file can be found at this link. The codes are in the refiterr script file.

Thanks,

Erik
