Cheat Sheet

Please use this page as a reminder and to copy and paste code snippets into your collection-yyQn.x and analysis ipython terminals.

To understand in more detail what the code does, please go to For XPD Users

Start a beamtime

  1. run bsui to start a collection ipython environment
  2. run the end-beamtime sequence if it has not been run
bt = _end_beamtime()
  1. run the start-beamtime sequence
bt = _start_beamtime(PI_last=<last_name_of_pi_on_the_SAF>, saf_num=<saf_number>,
                     experimenters = ['Emma', 'Watson', 'Tim', 'Liu'],
                     wavelength=0.184649)
  1. link bt to xrun
xrun.beamtime = bt

5. Copy the Excel spreadsheet provided by the experimenters with their samples in it to the xpdUser/import directory. Check that it has the name <saf_number>_samples.xlsx where the <saf_number> must match that of the current beamtime. If the user didn’t supply such a thing, then copy the file 300000_samples.xls from the xpdConfig directory (which is at the same level of the directory tree as the xpdUser directory) to xpdUser/import and edit the filename so that it has the saf_number of the current beamtime.

  1. load the info in the spreadsheet by typing:
import_sample_info()

Note

The sample objects may be updated at any time by editing the spreadsheet in the xpdUser/import directory and rerunning load_sample_info()

  1. calibrate the wavelength.

    FIXME

Things should now be set up for the user to run the experiment. Information about this is in the main part of the documentation.
