...
- consists in creating a new (MDS+) pulse file on the disk
- requires to have an existing 'database' (e.g corresponding to a directory when using the MDS+ backend) which will host the new pulse file

module load IMAS imasdb data_access_tutorial |
We can Let's check that the database has been successfully created:

$ ls -alh ~/public/imasdb/data_access_tutorial/ total 2.5K drwxrwsr-x 3 fleuryl fleuryl 4.0K Aug 31 10:09 . drwxrwsr-x 14 fleuryl fleuryl 4.0K Aug 31 10:09 .. drwxrwsr-x 13 fleuryl fleuryl 4.0K Sep 13 11:16 3 |
Some sub-directories have been created, they are used by MDS+ to organize the pulse files.
Now, the following code will create a new MDS+ pulse file for shot=15000, run=1 in the 'data_access_tutorial' database of the current user:
