usage

string lalinference_nest2pos.usage

(

void

)

Initial value:

=  '''%prog [-N Nlive] [-p posterior.hdf5] [-H header.txt] [--npos Npos] [--non-strict-versions] datafile1.hdf5 [datafile2.hdf5 ...]
 
%prog takes at least one nested sampling output file and outputs posterior
\tsamples. If more than one input file is specified, each file is converted,
\tthen posterior samples drawn according to the evidence of each.
\tIf the --npos option is used the algorithm
\twill draw approximately that number of samples from the posterior. This may
\tgive repeated samples in the output file. By default, the non-repeating
\talgorithm is used, but that may not produce enough samples.
\tThe input and output files may be in either HDF5 or ASCII format, with
\tASCII tables being deprecated. The type will be chosen based on the file extensions.
