A few more questions
1. How much memory do you have on your system? You can find it from the first line of /proc/meminfo It should be something like "MemTotal: 131781468 kB"
2. What environmental limits do you have? Send the result of the "limit" unix command
3. I put a new version of mri_fieldsign here https://gate.nmr.mgh.harvard.edu/safelinks/greve/mri_fieldsign. Can you run this version and send me the terminal output? Also, if you can run it outside of your bash script, it would be better.

External Email - Use Caution
Hi Doug,
Here is output of uname -a: Linux thalamos.nimh.nih.gov 3.10.0-1127.13.1.e17.x96-64 #1 SMP 2020 x86-64 x86-64 GNU/Linux. For the second command: Centos Linux release 7.8.2003 (Core).
My system has the newest AFNI installed, do you think that could be the cause of the problem?
Thanks for your help!
Xiaomin

No, sorry, When I run it on my system it works. If I can't replicate the problem, I can't fix it. I don't know why you get it and I don't. Can you send me your system specs, ie,
- run uname -a
- the contents of /etc/redhat-release (if it exists)

You sent me left hemi data, so I ran the command below mri_fieldsign --fs fieldsign.71.nii.gz --polar LOO.wedge.polar.lh.real.nii.gz LOO.wedge.polar.lh.imag.nii.gz --eccen LOO.ring.eccen.lh.real.nii.gz LOO.ring.eccen.lh.imag.nii.gz --s LOO --hemi lh --sphere But I also noticed that the command that you gave below is for the right hemi. Do you know if the left hemi works? On 7/11/2020 1:43 PM, Xiaomin Yue wrote: * External Email - Use Caution * Hi Doug, I used FS 7.1 under WSL to analyze retinotopy data. Since the ring and wedge were presented at a different frequency, the data had to be analyzed separately for each condition. To get the field sign, I had to use the mri_fieldsign function to combine polar and eccen data. However, an error happened with running mri_fieldsign: “Segmentation fault (core dumped)”.
