2pck

2pck is a program that used to be distributed with versions of XDS until the end of 2008. It serves to convert frames from a number of formats into the CCP4 "pck" compressed file format. Since version January-2009, 2pck has been superseded by the 2cbf program. However, there are detector types supported by 2pck that are not supported by either 2cbf or XDS itself. For those (e.g. SMARTCCD, MAC) it might make sense to convert the frames to pck format which also the latest XDS can read.

A Linux binary of 2pck is here.

This is a sample 2PCK.INP:
