So you want to run heimdall, here is wrapper class which will allow you to do just that.

Args:

dada_key (hex): use PSRDADA hexidecimal key
filename (str): process specified SIGPROC filterbank file
verbosity (str): v, V, g, G increase verbosity level
nsamps_gulp (int): number of samples to be read at a time
beam (int): over-ride beam number
baseline_length (float): number of seconds over which to smooth the baseline
output_dir (str): create all output files in specified path
dm (list): min and max DM
dm_tol (float): SNR loss tolerance between each DM trial
zap_chans (int): zap all channels between start and end channels inclusive
max_giant_rate (int): limit the maximum number of individual detections per minute to nevents
dm_nbits (int): number of bits per sample in dedispersed time series
gpu_id (int): run on specified GPU
no_scrunching (bool): don't use an adaptive time scrunching during dedispersion
rfi_tol (float): RFI exicision threshold limits
rfi_no_narrow (bool): disable narrow band RFI excision
rfi_no_broad (bool): disable 0-DM RFI excision
boxcar_max (int): maximum boxcar width in samples
fswap (bool): swap channel ordering for negative DM - SIGPROC 2,4 or 8 bit only
min_tscrunch_width: vary between high quality (large value) and high performance (low value)
