Showscan

Showscan is basically a simple HDF5 viewer application. It can be launched from Spock using the showscan command. Without arguments, it will show you the result of the last scan in a GUI:

Scan data viewer in action

showscan scan_number will display data for the given scan number.

Note

The showscan application can only read scans saved in the HDF5 format. Moreover, it opens the first file defined in ScanFile environment variable, so if you use multiple files, make sure the HDF5 format one is the first one on list.

The scan files are saved on the Sardana server machine, however showscan is running on the client one. If it’s not the same machine, you will need to share the scan files between machines, for example with NFS.

Note

If the path to the file on the server is different than on the client, you should use DirectoryMap environment variable to map server paths to client paths.
