I have imported star file and mrc stack from my Relion Extract folder and tried to run Auto Refine. It always finished the first iteration then returns with the errors below:
Error: File '/dev/null' couldn't be removed (error 13: Permission denied)
Error: Number of particles selected = 0; please change score threshold
float FrealignParameterFile::ReturnThreshold(float, bool)
Please let me know if there were solutions. Thanks!
