Where can I find a list of all possible commands and arguments for the msgen client?

You can get a full list of available commands and arguments by running msgen help. If no further arguments are provided, it shows a list of available help sections, one for each of submit, list, cancel, and status. To get help for a specific command, type msgen help command; for example, msgen help submit lists all of the submit options.

Where do I get the value for --api-url-base?

Go to Azure portal and open your Genomics account page. Under the Management heading, choose Access keys. There, you find both the API URL and your access keys.

Where do I get the value for --access-key?

Go to Azure portal and open your Genomics account page. Under the Management heading, choose Access keys. There, you find both the API URL and your access keys.

Why do I need two access keys?

You need two access keys in case you want to update (regenerate) them without interrupting usage of the service. For example, if you want to update the first key, you should have all new workflows use the second key. Then, wait for all the workflows using the first key to finish before updating the first key.

Do you save my storage account keys?

Your storage account key is used to create short-term access tokens for the Microsoft Genomics service to read your input files and write the output files. The default token duration is 48 hours. The token duration can be changed with the -sas/--sas-duration option of the submit command; the value is in hours.

What genome references can I use?

These references are supported:

Reference Value of -pa/--process-args
b37 R=b37m1
hg38 R=hg38m1
hg38 (no alt analysis) R=hg38m1x
hg19 R=hg19m1

How do I format my command-line arguments as a config file?

msgen understands configuration files in the following format:

  • All options are provided as key-value pairs with values separated from keys by a colon. Whitespace is ignored.

  • Lines starting with # are ignored.

  • Any command-line argument in the long format can be converted to a key by stripping its leading dashes and replacing dashes between words with underscores. Here are some conversion examples:

    Command-line argument Configuration file line
    -u/--api-url-base https://url api_url_base:https://url
    -k/--access-key KEY access_key:KEY
    -pa/--process-args R=B37m1 process_args:R-b37m1
