Dear AFNI Folks,

I've run into some trouble using 3dLME and referencing a separate dataTable file. Perhaps you'd be good enough to point out the error of my ways.

The following command works for me:

#!/bin/bash
3dLME \
-prefix LELMLeftLME \
-model "1+Time" \
-ranEff '~1' \
-dataTable \
Subj Time InputFile \
10124 T00 '/Volumes/Phillips/COG/AttentionAxis/10124/20060803/Deconvolve/LELMLeftIRESPZScore+tlrc[0]' \
10124 T01 '/Volumes/Phillips/COG/AttentionAxis/10124/20060803/Deconvolve/LELMLeftIRESPZScore+tlrc[1]' \
10124 T02 '/Volumes/Phillips/COG/AttentionAxis/10124/20060803/Deconvolve/LELMLeftIRESPZScore+tlrc[2]'


However, for this analysis I have many more subjects and time points, so many so that if the dataTable contents are passed to 3dLME via command line I receive this error:

./LELMLeftModelTable.txt: line 3: /opt/ni_tools/afni/3dLME: Argument list too long

Following the directions in the 3dLME documentation, I created a table called 'table.txt' such that the command cat table.txt returns this:

Subj Time InputFile \
10124 T00 '/Volumes/Phillips/COG/AttentionAxis/10124/20060803/Deconvolve/LELMLeftIRESPZScore+tlrc[0]' \
10124 T01 '/Volumes/Phillips/COG/AttentionAxis/10124/20060803/Deconvolve/LELMLeftIRESPZScore+tlrc[1]' \
10124 T02 '/Volumes/Phillips/COG/AttentionAxis/10124/20060803/Deconvolve/LELMLeftIRESPZScore+tlrc[2]'

I also created script file containing the call to 3dLME:

#!/bin/bash
3dLME \
-prefix LELMLeftLME \
-model "1+Time" \
-ranEff '~1' \
-dataTable table.txt

When I execute the script above from within the directory containing the 'table.txt' file I receive the follow error:

Error in if (len%%wd != 0) errex.AFNI(paste("The content under -dataTable is not rectangular !", :
argument is of length zero
Calls: process.LME.opts
Execution halted

Bizarrely, if the -dataTable flag references a file that does not exist, I receive the same error:

#!/bin/bash
3dLME \
-prefix LELMLeftLME \
-model "1+Time" \
-ranEff '~1' \
-dataTable nonexistent_table.txt


returns

Error in if (len%%wd != 0) errex.AFNI(paste("The content under -dataTable is not rectangular !", :
argument is of length zero
Calls: process.LME.opts
Execution halted


This leads me to think that there is some very simple problem with the way that I am formatting the call to 3dLME. Any suggestions would be much appreciated.

Also, because it may be relevant, afni -ver returns:

afni -ver

Cheers!
