=== DataTable ===
''3dMVM'' and ''3dLME'' can take an input table like ''3dMVM ... -dataTable @myfile.tsv''. Both are very particular about the format of the input file.

  * ''Subj'' must be the name of the first column (and thus the first word of the file)
  * ''InputFile'' must also exist and be a valid **3D** file. You will get an error if any row has an inputfile that is more than one volume (**4D**; file with many "briks"; ''3dinfo -nt'' > 1) and does not have a sub-brik specifier ( ❌''deconve_output.nii.gz''; ✅ ''deconv_output.nii.gz[Coef#0]'')

== Building ==
Here's example [[:tools:r|GNU R]] code to add ''InputFile'' to an existing dataframe ''df'' ((from Finn circa 2023-09))
<code=R>
path_prefix <- '/Volumes/Hera/Datasets/adept/data/tat2/sub-'
df <- df %>%
        mutate(InputFile = paste0(path_prefix, subjid, '_ses-0', visit, '_tat2.nii.gz')) %>%
        filter(file.exists(InputFile))
</code>

== Other Tools ==
  * ''[[https://github.com/lncd/lncdtools/blob/master/4dConcatDataTable|4dConcatDataTable]]'' (an [[:tools:lncdtools|lncdtool]]) reuses the same dataTable format to create 4D images useful for the "graph" view in [[:tools:afni_gui|AFNI's GUI]].
  * ''maskvolume'' uses 3dROIstats w/mask as input and mask to get ROI sizes in mm^3
  * ''[[tools:lncd:3dmaskave_grp|3dmaskave_grp]]'' uses 3dmaskave or 3dROIstats to get roi averages in parallel to a single file
