There are numerous ways to access your data. Each have their pro's and con's pros and cons which will be discussed. All data in is kept on SLAC's global file system and is available from all centrally managed hosts.
All experimental data is stored under /sdf/group/cryoem/exp/YYYYMM/YYYYMMDD-AA##
where Y is year, M is month, D is day, and AA## is the 4-character alphanumeric proposal number. Example: if your experiment name is 20180520-CS01
, then your data will be held under located at /sdf/group/cryoem/exp/201805/20180520-CS01
.
Permissions to access the data can be controlled via the elogbook https://cryoem-logbook.slac.stanford.edu/lgbk/experiments. One should add the SLAC unix ID whomever should have access to the data to the list of 'collaborators' for the experiment.
...
Globus
One can create a free globus Globus account at at https://globusonline.org. From there, one can download a local client (Globus Connect Personal) so that files may be copied to say your laptop, or staged to another Globus Endpoint that your institution may run.
...
You should use your SLAC Unix Account as credentials to log into slac#cryoem endpoint (once you have a globus idID).
SAMBA
If you are onsite at SLAC, you can access the data via samba/cifs. You should connect to zslaccfs
in order to browse the global directory. From there you can access the cryo-EM disks under cryoem
.

BBCP provides multi-stream parallel transfers of data that allows transfers speeds to be significantly higher than that of scp. Details TBD.
