Change FragPipe temp directory on Linux/Unix

[GregStacey]

I'm successfully running the headless version of fragpipe, but I'm encountering a problem when submitting it via scheduler on a cluster. When submitted, the cache directory is read-only (~/.config/FragPipe/fragpipe/) and the run fails. The full error log is below.

I suspect this can be solved on the cluster side, but I'm also curious if there's a way to change the cache path in headless mode. Thanks!

I think so. Can you try the approach in #306 (comment) to see if it works for you?

Best,

Fengchao

Thanks for the quick response. Unfortunately I get the following error about the X11 display

[fcyu]

You need to add the --headless flag (and other commands to set the workflow and manifest) so that FragPipe will run in headless mode. Without any flags, FragPipe runs in GUI mode.

Best,

Fengchao

[GregStacey]

Thanks again. I see my mistake!

Unfortunately export JAVA_OPTS=-Djava.io.tmpdir=/scratch/st-ljfoster-1/staceyri/isabela_fragpipe/tmp/ doesn't fix the error for me. I can see empty folders being made in the new tmp folder:

$ ls /scratch/st-ljfoster-1/staceyri/isabela_fragpipe/tmp/
af6fdd7f-da18-4dd1-b374-2cb499fafd15  d1d6cf4a-2265-4e16-bbaa-d6af9041dfab  e109884b-958b-468a-b85c-4f73c44d0e59  f06836aa-9c9f-4e8c-bb02-77224a71b88a
$ ls /scratch/st-ljfoster-1/staceyri/isabela_fragpipe/tmp/af6fdd7f-da18-4dd1-b374-2cb499fafd15/
$ 

But the same error persists where fragpipe tries to save files in the /home/ directory:

2022-07-08 15:11:15,601 ERROR - Error saving ui cache
java.nio.file.FileSystemException: /home/staceyri/.config/FragPipe/fragpipe/fragpipe-ui.cache: Read-only file system
...

I heard back from the cluster administrators and the problem is that /home/ doesn't exist on the compute nodes. I tried naively redefining $HOME but that also doesn't solve the issue for me. The submission script is below in case that's helpful. Again I don't see the error when just running /path/to/fragpipe on the head node.

# change temp folder
export JAVA_OPTS=-Djava.io.tmpdir=/scratch/st-ljfoster-1/staceyri/isabela_fragpipe/tmp/
# confirm temp folder is changed
echo $JAVA_OPTS

# change home folder
HOME=/scratch/st-ljfoster-1/staceyri/
echo ~

[fcyu]

Thanks for your feedback.

I think I found the cause of the issue. In Linux and Unix, FragPipe always save cache to HOME:

FragPipe/MSFragger-GUI/src/com/github/chhh/utils/CacheUtils.java

Line 96 in add8fbe

final String dir = OsUtils.isUnix() ? XDG_CONFIG_HOME + "/FragPipe" : SYS_TEMP_DIR;

For your case, can you try setting a XDG_CONFIG_HOME=<temp path> environment variable? Details of the code can be found from

FragPipe/MSFragger-GUI/src/com/github/chhh/utils/CacheUtils.java

Line 40 in add8fbe

return System.getenv("XDG_CONFIG_HOME");

Best,

Fengchao

[GregStacey]

Thanks, Fengchao. Adding the following lines to the submission script fixed the issue for me.

XDG_CONFIG_HOME="/path/to/working/directory/"
export XDG_CONFIG_HOME

[fcyu]

Thanks for the positive feedback.

Best,

Fengchao

[nyin01]

Thanks, Fengchao. Adding the following lines to the submission script fixed the issue for me.

XDG_CONFIG_HOME="/path/to/working/directory/"
export XDG_CONFIG_HOME

Hi! I'm running into the same issue but setting XDG_CONFIG_HOME alone didn't solve the problem for me. I'm running it on a docker image. Was setting the HOME the only modification you made? Thanks!

[guoci]

What error log did you get? Since you are running on a docker container, there should be no conflicts with the OS filesystem.
