... Transforms a qpoe file according to the specified parameters. ... Any type of filtering can be applied to the input qpoe file, including region filtering. In addition, the size of the output event record can be different from the size of the input event record. Of course, usually one makes the output record equal to or smaller than the input. If the output record size is made greater than the input record, a warning is issued and the ``extra'' part of the record is undefined.) ...
