path (str) –

select_data_files(datapath=None, name_pattern='', auto=True, load_hdf=False)

Provide the user with menu to select data files.

Finding the right data store is complicated as there are many kinds of data files

• If datapath is …RA_data/HDF5/… then the files could be .h5 (Ashish) or .hdf5 (Dean).

• If datapath is …RA_data/FITS/… then the extent is .fits.

• If datapath is …project_data/… then the extent is .pkl

• If datapath is …projects/… (default) then the extent is probably .csv or .dat or .prd.

:param datapath : path to top of the tree where the DSS subdirectories are :type datapath : str

:param name_pattern : pattern for selecting file names, e.g. source :type name_pattern : str

:param load_hdf : use RA_data/HDF5 directory if True :type load_hdf : bool

@para auto : take all files found :type auto : bool

Returns

list of str
