Dear all,
I have been using Brain Suite for two weeks and I really like it.
Unfortunately, I can’t find a file which should be created by SVReg according to the software description. I would be very glad if someone could help me!
By using Matlab, I was able to read vertex-wise cortical thickness. In fact, I am more interested in the average cortical thickness of labeled structure. The description of the output of SVReg says that there is a file called ‘fileprefix.roiwise.stats.txt’ which contains the volume and (where applicable) average cortical thickness of labeled structure. However, I am not able to find this file in the folder containing the SVReg outputs. I have tried SVReg several times. How can I create the file ‘fileprefix.roiwise.stats.txt’?
Thank you very much for your help!

The file should have been generated. Which folder are you checking and can you please give me a list of files that are generated? Can you please give more information about version and platform that you are using? Also did you notice any error during the processing, did the sequence finish successfully?

Dear Anand,
thank you very much for your quick answer!
I am checking the folder to which I saved the files created by Cortical Surface Extraction and SVReg using the GUI. The folder therefore contains the following files:
the nii-file
fileprefix.bse.nii
“.mask.nii
“.bfc.nii
“.brain
“.cerbrum.mask.nii
“.cortex.dewisp.mask.nii
“.cortex.scrubbed.mask.nii
“.cortex.tca.mask.nii
“.hemi.label.nii
“.init.cortex.mask.nii
“.inner.cortex
“.inner_skull
“.left.inner.cortex
“.left.mapped.dfc
“.left.mid.cortex.svreg.init
“.left.pial.cortex
“.mask.nii
“.outer_skull
“.pial.cortex
“.pvc.frac.nii
“.pvc.label.nii
“.right.inner.cortex
“.right.mapped.dfc
“.right.mid.cortex.svreg.init
“.right.pial.cortex
“.scalp
“.skull.label.nii
brainsuite_labeldescription

Furthermore, the folder contains the folder fileprefix.svreg.tmp. In this folder I also could not find the file ‘fileprefix.roiwise.stats.txt’
I use Brain Suite 15b and installed Matlab Runtime R2012a. My PC runs Windows 7.
I didn’t notice any error. I also tried it several times on another Windows PC with different nii-files. Again, I could not find the file.
Is this file created automatically by SVReg using the GUI or do I have to do anything special to have it created?
Thank you very much for your help!
Kind regards,
Christian

Based on this, I think the SVReg sequence has not finished. There must be error. If you can try again and send us a screenshot of when the sequence stops, that will be helpful. When the SVReg sequence finishes (cmd line or gui) it generates the following outputs. SVReg generally takes 1-2 hrs.

I tried it again. Unfortunately, again I could not find the file.

This is what I can find in the Brain Suite Log after running Cortical Surface Extraction and SVReg using gui. The nii-file is called ‘20150427’ and the folder I chosed to save the files to automatically is called ‘TEST’.

There is no warning that SVReg has not worked properly. After SVReg has finished the Cortical Extraction Sequence Window ist still open. It says ‘finished registration and labeling’ and 100% are achieved.
When I use gui I can choose the folder to which the files are saved to automatically. I can find all the outputs of Cortical Surface Extraction and SVReg in the selected folder called ‘Test’ after the SVReg has completed but not the file ‘fileprefix.roiwise.stats.txt’. The Windows Explorer doesn’t find the file in any other folder of my PC.
Thank you very much for your help!

[Anand Joshi]

The file you are looking for is 20150427.roiwise.stats.txt right? fileprefix should be replaced by name of the subject. I am asking just to be sure.

[christ21]

I am sorry. Yes, I mean I am looking for 20150457.roiwise.stats.txt.

[christ21]

I could solve the problem. The file I am looking for is created when I start ‘generate_statistics_xls’ by using the commanding line.
However, thank you very much for your support and help!

[Anand Joshi]

Great! We will check if there is any issue in generating this file when the sequence is run through the gui and fix it. Thank you for reporting.

[christ21]

Thank you very much!

[Anand Joshi]

I tried it now but the stats.txt file was generated as expected. We will investigate it if we can reproduce the issue or if it reoccurs. Glad that things are working for you now.
