Having issues importing particles from relion

I am getting this error when trying to import particles from relion. Any suggestions or workarounds would be amazing.

It looks like your particles are in float16 format which is not compatible with cryosparc.

Best,

@ammariesm float16 support is available through a recent patch for version 3.3.1. Please see the patch announcement for additional details.
