Hi,
I have used afni for many years with my timing files in columnar form. I'd never had problems with that, but now, it seems to want the files in row format. I have fixed that using 1dtranspose, but now I have a new problem:
I am using a task with 2 runs. I extracted the timing for each block from the start of the block. Now I get warnings that I only have 1 row for two blocks for each condition. Is there a way to address this?
Also, I am getting warnings because the timing files for the two blocks are similar. I could fix that, I guess, by adding the offset of the end time of the first block, but I'm not sure how to do that.
It is okay to use the single column format, where each time is with respect to the beginning of the first run, though we generally suggest one row per run, since it is a little more visually clear. But either should work.
Can you provide more details, actual warning messages, or clips of the timing file themselves? Maybe I will just send you a private message, and you can send me the problematic timing files, perhaps along with the text output from 3dDeconvolve. Does that seem okay?
It looks like you might just combine each run 1 and run 2 pair into a single file. For example:
cat rating*t.1D > ratings_both.1D
Then there would be only one ratings class in the regression. It should be just like you would do with a single column, but these timing files would have 2 rows (one row per run).
Still, this should also work with the single column format.
Please let me know if you would like to go into more detail, or even to have a quick zoom chat.
