Click ‘Set XY Box’ and use the square to select the + beam centre. Right click and select ‘SetXY box coords’. Then highlight the + scattering files in the ‘scattering files table’ at the configuration for which + you’ve just set the empty beam transmission, and click ‘calculate selected files’ in + the Calculate transmissions window. The S_Transmission column in the + ‘ScatteringFiles’ window should now be populated. + Repeat this step for the other configuations. + Click ‘done’ when finished with transmissions’. If you click ‘File catalog’ the + data File catalog window will be updated, and you should be able to see the + transmission values.

(If you are using an empty cell from a previous run, you need to copy the file to + the current directory – these will have different beam centres, unless obviously far off + warnings about this can be ignored). + ‘Sensitivity’.
