Create tool to extract scan description from pfile

[jcohenadad]

Based on the pfile.Help, here's what's available:

Pfile('P12345.7')
Pfile('P12345.7', ['No-Anonymize' | 'Partial-Anonymize' | 'Full-Anonymize'], ['Single-AcquisitionMode' | 'All-Acquisitions' | 'All-Available-Acquisitions' | 'Raw-Data' | 'No-Compression'])
    Load Pfile into memory. 'Full-Anonymize' is used by default for the Anonymization Mode.
    Load Pfile into memory. 'All-Available-Acquisitions' is used by default for the Read Mode.
    DICOM images can be created with 'Full - Anonymize' Pfile data.

header = pfile.Header()
    header is a python dictionary
    header informtaion contains the entire POOL_HEADER structures
    Once the header information is available, we can access any member of the header, example:
rev = header['rdb_hdr_rec']['rdb_hdr_rdbm_rev']
scan_date = header['rdb_hdr_rec']['rdb_hdr_scan_date']
coil_name = header['rdb_hdr_image']['GEcname']

metadata = pfile.MetaData()
    metadata is a python dictionary
    metadata informtaion: phases, slices, echoes, channels, acquiredYRes, acquiredXRes, imageXRes, imageYRes.

kSpace = pfile.KSpace(slice, echo)
kSpace = pfile.KSpace(slice, echo, channel, phase)

corners = pfile.Corners(slice)
   corners is a Python dictionary.

orientation = pfile.Orientation(slice)
   orientation is a Python dictionary.

info = pfile.Info(slice)
info = pfile.Info(slice, pass)
   info contents: slice number, frequency shift, phase shift, slice shift 
   frequency scale, phase scale, slice thickness scale
   info is a python dictionary

However, I was not able to find information about the scan description (a.k.a. "SeriesDescription" in the BIDS world), that is: the information that is manually entered at the console for the scan, such as "T2_axial".

Maybe this is where the info is?

Maybe the info is in the files ref.dat & vrfg.dat?
