Patch Motion Correction error

Hi all,
There is an error messenge when I do the Patch motion correction. Does anyone know what happen?

Error occurred while processing J3/imported/011447104231546704801_20170629_00022_frameImage.tiff

Any help is appreciated

Looks like a corrupt micrograph. Check your micrographs, check your filesystem for corruption (and/or disks for bad sectors) or a failure in the network connection if a network filesystem.

Hi @cafbi,

Is your installation running under docker, or is there anything else in any way peculiar about your installation? Is it a cluster? Also, how much memory does your machine have?

Regardless, though, you can probably avoid this by opening the file /path/to/cryosparc_worker/ and adding the line export CRYOSPARC_TIFF_IO_SHM=false. That will turn off shared-memory I/O, wherein we read an entire TIFF file into memory before decompressing it (rather than decompressing it piece-by-piece directly from disk). We added this as an optimization, and turning this off may have a negative performance impact if you’re using a cluster file system like Lustre.
