Hi @Lulu, the vseries open *.mrc command is trying to open the .mrc files that you would have downloaded as the output of “3DVA Display” jobs.
You would have downloaded a .zip file, and if you decompress that, you will find inside a series of .mrc files.
You should replace vseries open *.mrc
with the correct path to your downloaded series. So for example: vseries open ~/Downloads/cryosparc_PXX_JYY/*.mrc
This wil actually open the right files, and then the rest of the command will create the movie.
