sep_reed("in",sepdata)will read in a SEPlib77 or SEPlib90, header or no headers, regular or irregular, traces in order or out of order dataset into the sep_90 type.
In addition with optional arguments the user can:
Just as sep_reed simplified reading in datasets, sep_rite and finish_tags making writing datasets easier.
sep_rite provides in its simplistic form a two argument call:
to write out any variety sep_90 dataset. In addition it provides
numerous optional arguments to write out subsets or too subsets of
a SEPlib dataset on disk.
3-D datasets are usually irregular and are not possible to keep in core. As a result we generally process the dataset in sections, reading only what we need and writing what we are finished with. When writing these datasets to disk, the total number of traces and headers is not known until the very end. finish_tags provides the necessary mechanism to deal with this problem. Every time a call to sep_rite is made the number of traces written to a given tag is recorded. A call to finish_tags writes out to all the output tags the total number of traces written.
