The File menu offers several options, the two you need to know about immediately are File=>Meta Data and File=>View Data.
The File=>Meta Data item allows you to inspect the information known about your data
this information is known as ``meta data'', and is ``data about (describing) your data''. Initially little will be known about the data, but more meta-data will accumulate as you perform operations on the data.
The File=>View Data item will pass your data to the Starlink TOPCAT application where you can carry out sophisticated selections, cuts and and analysis on your time series data.
At the moment the only way to reimport you data into FROG is to save it as a FITS format file and load it back into the application using the File=>Open Time Series item. In the near future TOPCAT should offer the option to push your data back to a running instance of FROG using web services.
