The cryoSPARC master node hosts the web server and manages job resource allocation.
Workstations or master nodes with a cryosparc_master
installation have access to cryosparcm
, cryoSPARC's built-in command-line utility for all administrative, management and advanced usage tasks.
To use it, log into the machine onto which cryoSPARC was installed. Open a Terminal running a shell (such as bash
) and enter any of the commands described below.
cryoSPARC's installation script adds the location of cryosparcm
to the $PATH
environment variable via ~/.bashrc
for the <cryosparcuser>
UNIX user account (see Prerequisites & System Requirements for details).
For systems that do not support this, navigate to the cryosparc_master
installation directory and run ./bin/cryosparcm
instead of cryosparcm
See Software Updates for details.
Apply the latest patches available for your installed version of cryoSPARC without doing a full version update.
Specify the --help
flag to see full usage
$ cryosparcm patch --helpusage: cryosparcm patch [-h] [-f] [-y] [--check] [--download] [--install]​Download and apply cryoSPARC patches. Run cryosparcm patch to automaticallyinstall the latest patches on master and worker nodes​optional arguments:-h, --help show this help message and exit-f, --force install latest patch again even if already installed-y, --yes confirm patch installation without prompt--check check to see if a patch is available--download download master and worker patches for manual installation--install manually install a downloaded patch file
Frequently used commands:
cryosparcm patch
: Automatically installs the latest patches on workstations or master node and connected workers. Not recommended for clusters: Use the --download
and --install
flags instead.
cryosparcm patch --force
: Reinstalls the latest patches in case something went wrong with a previous attempt
cryosparcm patch --check
: Shows information about the latest patches without installing
cryosparcm patch --download
: Downloads the latest patches without installing them. Follow the resulting instructions to install the master and worker patches
cryosparcm patch --install
: Run this command immediately after a --download
to install the patch on the master node.

​
Some patches require restarting cryoSPARC. After running cryosparcm patch
, when prompted restart with cryosparcm restart
.
Configures cluster installation. See the Download and Installation page for details.
Use with one of the following sub-commands.
Writes config and script template files to current working directory, cluster_info.json
and cluster_script.sh
respectively.
Examples are available for Portable Batch System (cryosparcm cluster example pbs
) and SLURM (cryosparcm cluster example slurm
) schedulers. Other systems are similar; run one of the two cluster example
commands and modify the output files accordingly.
Outputs the existing config and script to current working directory for the cluster with the given name.
Reads cluster_info.json
and cluster_script.sh
from the current directory. Connects a new or updates an existing cluster configuration using the name from cluster_info.json
.
Removes a cluster configuration from the scheduler.
The following commands are only allowed to be executed by <cryosparcuser>
(the user that installed cryoSPARC), and can only be executed on the master node. If these conditions are not met, you may see the following error:
You can mitigate errors temporarily by specifying the CRYOSPARC_FORCE_HOSTNAME
variable just before calling the command:
cryosparcuser@wrong.server:~$ CRYOSPARC_FORCE_HOSTNAME="true"cryosparcuser@wrong.server:~$ cryosparcm status----------------------------------------------------------------------------CryoSPARC System master node installed at/home/cryosparcuser/cryosparc/cryosparc_master----------------------------------------------------------------------------​cryosparcm process status:...
If this error message is incorrect (the hostname specified in the error message is actually the same host, just a different identifier), you can set the hostname that the management script will use to compare by adding the variable CRYOSPARC_HOSTNAME_CHECK
to cryosparc_master/config.sh
. You can also set CRYOSPARC_FORCE_HOSTNAME
in this file to permanently suppress this error.
File: /home/cryosparcuser/cryosparc/cryosparc_master/config.sh​export CRYOSPARC_LICENSE_ID="xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"export CRYOSPARC_MASTER_HOSTNAME="uoft"export CRYOSPARC_DB_PATH="/home/cryosparcuser/cryosparc/cryosparc_master"export CRYOSPARC_BASE_PORT=61000export CRYOSPARC_HOSTNAME_CHECK="uoft"
Prints out current status of the cryoSPARC master system, including the status of all individual processes (database
, webapp
, command_core
, etc). Also prints out configuration environment variables.
Starts the cryoSPARC instance if stopped, including the database, the command server, the web interface, etc.
All processes start in the background, including all jobs and the web interface; the command line may be closed after running start
.
Stops the cryoSPARC instance if running. This will gracefully kill all the master processes, and will cause any running jobs (potentially on other nodes) to fail.
Equivalent to running cryosparcm stop && cryosparcm start
Show a summary of how many jobs are active
Backs up cryoSPARC database. By default, creates a file in cryosparc_master/run/db_backups/
with the current timestamp in its name.
To change the output location, specify the --dir
or --file
flag.
cryosparcm backup \--dir=/path/to/backups \--file=custombackupfile
The cryoSPARC system maintains several log files for its various processes that help with debugging any components of the cryoSPARC system that are not working.
Shows the output log of the master node process denoted by <process>
which can be one of the following:
command_core
command_vis
database
webapp
For example
cryosparcm log command_core
The log is live and automatically updates while the command-line remains open and new data is added to the log. To stop live updates and return to the shell, press control C
on your keyboard, and then q
To save the full log, redirect the output to a file
cryosparcm log command_core > command_core.log
To show only the last lines of the log, use tail
cryosparcm log command_core | tail -n 1000
This show the last 1000 lines of the log.
Shows a live output log for job JXX
in project PX
. Includes the standard input and error from the python process for the job.
For example, to show the output of Job 123 in Project 3, run the following
cryosparcm joblog P3 J123
joblog
shows the full stdout
for the job, which is more comprehensive than the job log in the web interface and is more helpful for debugging.
To stop logging, save the full log or view only the last few log lines, see instructions for cryosparcm log
​
Outputs a table of users registered with the system, including their names, email addresses and admin status.
Creates a new user account for log in through the web interface. Full use:
cryosparcm createuser \--email "<email address>" \--password "<new password>" \--username "<login username>" \--firstname "<given name>"\--lastname "<surname>"
Resets the password for indicated user with the new <password>
provided. Full use:
cryosparcm resetpassword \--email "<email address>" \--password "<new password>"
Updates a user profile to change the user name or set admin privileges. Full use:
cryosparcm updateuser \--email "<email address>" \--password "<current password>" \--name "<new name>" \--admin "<'true' or 'false'>"
The --name
and --admin
flags are optional.
Other than for the first-created user account, new users do not have administrative privileges applied by default. Following creation of the first-created user account, other accounts can also be created through the user interface if preferred:
Prints a list of environment variables for use in a command-line shell to replicate the exact environment used to when running cryoSPARC processes.
Run this command with eval
to define the variables output by the env
command.
eval $(cryosparcm env)
This may be used to, for example, run the Python distribution that ships with cryoSPARC.
Runs a command using with cryoSPARC's command-line interface
cryosparcm cli <command>
See the full command reference
Runs an an interactive cryosparc shell that connects to the master processes. Use this to interactively run Python commands in the same environment as cryoSPARC.
Similar to cryosparcm cli
, but for running interactive commands with CryoSPARC Live.
Additional details coming soon.

Starts a mongo
shell for cryoSPARC's local mongoDB instance.
Execute a shell command in cryoSPARC's shell environment, such as Python. Equivalent to calling eval $(cryosparc env)
followed by another shell command.
