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 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 /gpfs/slac/cryo/fs1/exp/201805/20180520-CS01.

*** Since January 2021, data are temporarily stored on a different filesystem, please use the path:

/sdf/group/cryoem/exp/YYYYMM/YYYYMMDD-AA##.

Permissions to access the data can be controlled via the elogbook https://cryoem-logbook.slac.stanford.edu/lgbk/experiments. One should add whomever should have access to the data to the list of 'collaborators' for the experiment.

1. Install cifs-utils. sudo apt-get install cifs-utils

2. Create a directory where you want to mount it. sudo mkdir /mnt/slac

3. Code Block
   sudo mount -t cifs -o username=SLAC_USERNAME,vers=1.0,domain=slac,uid=`id -u` //zslaccfs.slac.stanford.edu/cryoem/ /mnt/slac

   Note that the uid is important so that you as user can have the correct permissions on your local desktop.

Alternatively, you can mount it via command line.

SSHFS

You can also use the FUSE based SSHFS to mount the filesystem via ssh. It is recommended to ssh into dtn02.slac.stanford.edu in order to use this method.

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