You will first need a SLAC unix computer account to be access your data.
There are numerous ways to access your data. Each have their pro's and con's which will be discussed. All data in kept on SLAC's global file system and is available from all centrally managed hosts.
All experimental data is stored under /gpfs/slac/cryo/fs1/exp/
and is organised within a directory that is the month of the experiment. eg if your experiment name is 20180520-CS01
, then your data will be held under /gpfs/slac/cryo/fs1/exp/201805/20180520-CS01
.
...
The Endpoint for SLAC CryoEM's data is at slac#cryoem
.
You should use your SLAC Unix Account as credentials to log into slac#cryoem endpoint (once you have a globus id)
Please note that currently, you must request access to be able to use the slac#cryoem
endpoint. Please send an email to ytl@slac.stanford.edu.
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
.
...
Using SSHFS the filesystem will be mounted locally so that you may browse the directory as you would with SAMBA etc.
BBCP
blahBBCP provides multi-stream parallel transfers of data that allows transfers speeds to be significantly higher than that of scp. Details TBD.
Summary
