Dear community,
I am processing helical particles in relion 3. I have tried to run 3D
classification with and without symmetry and with and without helical
reconstruction. When helical reconstruction is activated there is no
problem but when I try to run the classification with no helical
reconstruction the process die. If using GPUs for acceleration, the
error message is "CudaCustomAllocator out of memory" despite the
particles box is just 100 pixels. If running with CPUs, it invokes
MPI_ABORT in the 1st iteration or as late as the 2nd iteration.
Smaller subsets of the same particles have the same problem.
However, if I run a 3D classification I run before with a different
particle selection and box (but from the same dataset and
2Classification, but different class selection, more strict) there is
no problem.
Do you have any clue of what is happening?
Thank you very much.
Kind regards,
David.
