NMRPipe Processing Functions

This particular reference page lists the specific processing functions that can be used in an nmrPipe processing pipeline (via nmrPipe -fn ...), for example "FT", the Fourier Transform function.

Like FT, many of these functions frequently in typical processing schemes. Some functions and options, however, may rarely be used, were added only for development purposes, or may be superseded by other functions. In an attempt to indicate which functions and options are used most frequently, this reference list includes an instance count. In the current version of this reference list, the instance count tallies how often NMRPipe's developer Frank Delaglio has used a particular function or option in a script during both routine use and research and development of the software. Note that this scheme will underestimate the uses of functions such as SAVE which are primarily used interactively, and not within scripts.
