tmp2ind_T1.sh about citatlaskit

[ucigrangers]

Looks like it ran! Thanks so much for your attention on this and rapid reply.
I see it output the "Prob atlas in individual space : pA_tmp2ind.nii.gz" into the current directory and consistently labelled but I believe there was an error in the output of the "Template T1 in individual space : T1w_tmp2ind.nii.gz".

Could this be labelled something else by the script? I see several other files generated but unsure what to make of this extra output and what is the T1 template in individual space if labelled something else. Here's an example of the extra files. I'm guessing from the warp log file that TMP2IND_Warped.nii.gz is the one I am looking for?

Hi Steven,

Really happy to hear you like the atlas!

I'll try to answer your questions in order:

1. The tmp2ind_T1.sh script actually warps the atlas into the individual space (ie the opposite direction from the one you stated above) - didn't want this to cause confusion down the line.

2. The third argument should be a 4D Nifti probabilistic atlas like CIT168_pAmyNuc_700um_MNI.nii.gz. FSL also uses this format for the Harvard-Oxford probabilistic atlases (see for example $FSLDIR/data/atlases/HarvardOxford/HarvardOxford-cort-prob-1mm.nii.gz in a typical FSL 5 installation). Each 3D volume in the 4D data is a separate probabilistic map for a given tissue label (voxel intensity in range 0.0 to 1.0).

3. The "i" and "p" prefixes in the filename refer to "integer-valued" and "probabilistic" labels respectively. We've actually moved to "d" (for deterministic) for the integer-valued labels. These would be equivalent to something like HarvardOxford-cort-maxprob-thr25-1mm.nii.gz in the FSL installation and would be 3D volumes.

4. Apologies, I'm not sure I completely understand what you're planning on exporting as text for further analysis. Voxel values from the warped atlas or individual data, calculated volumes of subnuclei? Let me know and I'll try to dig into that a bit further for you.

It looks like the script isn't parsing the command line arguments correctly, since there's no filename string following "Individual T1:", etc. Try making the script executable (chmod +x tmp2ind_T1.sh) then rerunning without the leading "sh" in your command line. Let me know if filenames start to appear in the initial output text from the script.

[ucigrangers]

Thank you so much for the rapid reply!
My misunderstanding, but that will work great. Thanks for clarifying points 2 and 3.

My apologies for the confusion on my last question, let me rephrase. I am hoping after warping the T1 atlas and the probabilistic atlas to my structural scans that I would then be able to access the corrected NIFTI file format for each of the subfields in the output separately.

[ucigrangers]

In addition, I have made tmp2ind_T1.sh executable but am still running into the same issue with and without the leading "sh". I presume since the shell and all necessary files are in the same directory I don't need to specify a path for each argument.

I didn't spot this first time round, but do you want the leading "/" for all your image files? Are they all in the root directory or the current directory? If the latter, you can either drop the "/" completely or prefix the filenames with "./"

Also, try running the script with bash rather than sh.

[jmtyszka]

I've simplified the argument handling so that both tmp2ind_*.sh scripts no longer need the argument key (eg -t1i). Try pulling the latest version (git pull ...) and see whether this fixes the weird argument handling you're experiencing. Tested this under macOS Sierra. Both "sh --version" and "bash --version" indicate that "GNU bash, version 3.2.57(1)-release (x86_64-apple-darwin16)" is the underlying shell. You might want to check on your Ubuntu system too.

Hi Steven,

Glad this worked out! I've fixed the issue with renaming the warped template T1 too (there was an extra underscore in the command). Let me know if everything works now and I'll close the issue.

Cheers - Mike
