                XXX.00 is optional zerofield baseline. XXX.70 is alteration check.
                syntax in sio_magic is: -LP CR xxx,yyy,zzz,.....xx -A
                where xx, yyy,zzz...xxx  are cooling rates in [K/minutes], seperated by comma, ordered at the same order as XXX.10,XXX.20 ...XX.70
                
                No need to specify the cooling rate for the zerofield
                It is important to add to the command line the -A option so the measurements will not be evraged.

        UCSC_leg_magic.py [command line options]

    OPTIONS
        -h: prints the help message and quits.
        -usr USER:   identify user, default is ""
        -f FILE: specify  input file, or
        -fin INDEX: specify  index file for reading whole directory: default is index.txt
        -F FILE: specify output file, default is magic_measurements.txt
        -Fsa: specify er_samples format file for appending, default is new er_samples.txt
        -spc NUM : specify number of characters to designate a  specimen, default = 1
        -loc LOCNAME : specify location/study name
        -A: don't average replicate measurements
       Sample naming convention:
            [1] XXXXY: where XXXX is an arbitrary length site designation and Y
                is the single character sample designation.  e.g., TG001a is the
                first sample from site TG001.    [default]
            [2] XXXX-YY: YY sample from site XXXX (XXX, YY of arbitary length)
            [3] XXXX.YY: YY sample from site XXXX (XXX, YY of arbitary length)
            [4-Z] XXXXYYY:  YYY is sample designation with Z characters from site XXX
            [5] sample = site
            [6] all others you will have to either customize your
                self or e-mail [email protected] for help.
