Hi AFNI folks,

I'm currently testing the ETCA method on some data, and while it produce output that makes sense (in that it is similar to the standard 3dttest output) it is producing errors that do not.

Specifically, it states that it cannot load a few 1D files during processing, but in examining the folder those files are present, and contain data. From looking at the output in the terminal window it seems that perhaps there was an attempt to load the files before they were written. It is just a error that doesn't crash processing, so I am not sure if this is normal or expected.

Relevant output:

Could this be due to parallel processing being used? Thanks for the help, just want to make sure the output is valid.
