Hi @nfrasser,
Thank you for your reply. I initially tried to import my raw files in .mrc format in cryoSPARC but I encountered the following error. 
The data were collected using Serial EM where mrc file stores 4 bit integers. So I tried to follow the thread (Importing mrc movies) and performed the initial steps of importing movies, motion correction and, CTF estimation outside cryoSPARC (in Relion v3.1). If I cannot import the micrographs.star or ctf.star files in cryoSPARC and cannot use the raw files in cryoSPARC, can you please suggest to me how should I proceed further?
Thanks,
Gundeep
