Import >100 micrographs err V2

When I try Import micrographs less than 10 it’s fine but when try more than hundred there will be an err, suppose something with the cache? but increase the value of cache_reserve_mb doesn’t help. Thanks for help


Hi @zjr, can you please post an image of the traceback?

HI @spunjani Here is the traceback:

HI @zjr, this probably means that one of the files included in your wildcard selection is actually blank, or not an .mrc file, and therefore its header is empty. In the file browser, after you entered a wildcard selection, the list view will update to show you only what is selected. If you scroll through that list and see any files with size 0 or that are not mrc files, that might be the culprit.

Hi @apunjani

you’re right
thanks for the help
