The MFOLD program unfolds a folded spectrum.
The MFOLD program is called as follows (all parameters must be specified on one line):
<Machine ID>mfold <name_s> <expno_s> <procno_s> <disk_s> <user_s> <name_d> <expno_d> <procno_d> <disk_d> <user_d>
The parameters must be followed by four numbers per dimension in the spectrum:
<lower> <upper> <direction> <sign>
The unfolding is done by replicating the spectrum in one or more of the dimensions. If <lower> and <upper> are zero for a dimension, this dimension is not touched. Else <upper> - <lower> copies are made.
<direction> can be -1 or 1. -1 means that every odd copy will be reversed.
<sign> can be -1 or 1. -1 means that every odd copy will be inverted.
