Construct filenames for SNS instruments

[Stuart Campbell]

Basically the functionality of FindNeXus.

This depends on the interface to the catalogue database #1404.

This ticket might already exist somewhere but I couldn't find it.

I am going to close this for this iteration as it will construct the correct filenames if the data files exist on your data search path.

The catalogue search will be in the next iteration (it is waiting on getting details on the back end web services)

• This only seems to work for me if I specify the instrument short name too, e.g. : FileFinder.findRuns("IRS26173")
• No delimiter tag is specified in the facilities.xml file, as far as I can tell.
  • I did not get it to work for SNS instruments.
• Did not seem to find the default instrument (when selected inside the GUI) except when the short name and the long name were the same.

I have tested using LoadNexusMonitors using a sequoia run ... method I used...

add /SNS/SEQ/IPTS-3332/0/7573/NeXus to my Data Search Directories

Then I can specify the run by either SEQ7573 or SEQUOIA7473

Works for me!
