      We have been having troubles with SVreg aborting when used from the command line.
      BUT, only on some machines. Seems to run fine on the same machines from the GUI.
      Have tried the commands from both v18a and 19a with same result. The svreg.exe is called from within a Matlab script.

      I think I have found the source of the command line error:
      “The whole surface volume registration and labeling sequence takes about 90-100 min.
      Starting parallel pool (parpool) using the ‘local’ profile … Error using parpool (line 103)
      You requested a minimum of 3 workers, but the cluster “local” has the NumWorkers property set to allow a maximum of 2 workers. To run a communicating job on more workers than this (up to a maximum of 512 for the Local cluster), increase the value of the NumWorkers property for the cluster. The default value of NumWorkers for a Local cluster is the number of cores on the local machine.
      Error in svreg (line 169)”

      So 2 core machines fail but 4 core machines do OK. Is this something you can address in the command line tool? Or do I have to try to modify the minimum number of cores in Matlab on every machine?

      Thank you for using BrainSuite and reporting this issue.
      You can run the svreg on the command line in a single threaded mode using -U flag.

      Yes! That did start the process.
      But it stops after a few minutes:

      But, oddly, if I look in ‘C:\Users\LARRYO~1\AppData\Local\Temp\Larry Olson\mcrCache9.0\svreg_0\toolbox\images\images\private\imhistc.mexw64’, imhistc.mexw64 is there

      See above. The svreg.exe with -U failed when I called it from Matlab 2019a. I just ran exactly the same call from the command prompt in Windows and it worked perfectly. I am puzzled…

      Did you install 32 bit windows MCR by any chance? A 64 bit version is required.

      No, it is 64 bit MCR
      It works from the GUI
      It works (with the same DOS command) from the Windows command prompt
      *It just aborts part way through (with the same DOS command) when started within Matlab

      (MCR_R2015b_win64_installer.exe)
      (but I also have other versions installed for creating Matlab standalone programs)

      That is so puzzling

      It might be that it is trying to use a different runtime version when called from matlab.
      Note that the environment variables and the path is different in dos and in matlab.
      check environment variables in matlab by typing env. Make sure that the correct MCR is first on the path.

      “check environment variables in matlab by typing env”
      >’env’ is not recognized as an internal or external command, operable program or batch file.
      (On Windows here)

      Actually I have only one Matlab Compiler Runtime: 7.13
      But 3 Matlab Runtimes: 9.0, 9.5, 9.6

      Not sure how to check environment variables…

      Can you just type path in the matlab command window?

      How are you running the svreg execuable from witin matlab? Are you using !svreg.exe …. ?

      Can you send me steps to reproduce the issue?

      Of course this is done after having run the Cortical Extraction Sequence first.
      Then, here is a bit of the Matlab code used to call svreg:

      Name = ’xnrT1.nii.gz’ %(skull stripped T1)
      basename = string(name(1:(length(name)-7))) %(.nii.gz extension)
      st=’svreg.exe ‘+ basename + ‘ -U’
      dos(st)

      This results in:
      basename= ‘xnrT1’
      st=svreg.exe “C:\Users\Larry Olson\Desktop\jtTestCase\BS”\xnrT1 -U
      these are the errors (from running the script OR from pasting into matlab command window):
      …curvature resolution 8/10
      curvature resolution 9/10
      curvature resolution 10/10
      Multiresolution curvature maps are calculated
      Computing additive curvature

      Curvature registration at resolution 1/4

      ans =
      -1

      Note I pasted the exact same call into a DOS Command Prompt, and it ran all the way through:
      svreg.exe “C:\Users\Larry Olson\Desktop\jtTestCase\BS”\xnrT1 –U

      Had to use the –U flag because this machine is only a dual core i5
