Particle Import Error

solved

(Hongjiang Wu) #1

Dear all,

I’m having errors when trying to import particle stacks into cryosparc with the following error log:

Traceback (most recent call last):
  File "cryosparc2_master/cryosparc2_compute/run.py", line 78, in cryosparc2_compute.run.main (/home/installtest/deps_manage/cryosparc2_package/deploy/stage/cryosparc2_master/cryosparc2_compute/run.c:3954)

KeyError: 'psize_A'

It only happens when I ignore the raw data in other words only import the coordinates and link to source micrograph.

Thank you all!

I’m also getting this error – did you ever find a solution?

thanks!

I was able to get this to work by making a simplified version of my .star file for import, containing just the micrograph name and X/Y coords. eg:

data_images

loop_
_rlnCoordinateX #1
_rlnCoordinateY #2
_rlnMicrographName #3

Of course this means that you’re losing any shifts and angles for you particles, however.

Other than changing the .star file, I was following the process described here:
