CCP4 truncate

Some background is given here. This problem can affect SHARP/autoSHARP users in two ways:

• If starting from MTZ file(s) containing already amplitudes and anomalous differences (including their sigmas):
• these should ideally have been generated via a functioning TRUNCATE versions (prior to CCP4 7.0.039 or after 7.0.056);
• alternatively, a different program for intensities-to-amplitudes (and anomalous differences) could be used - e.g. CTRUNCATE or XDSCONV (if coming from XDS processing).

• If startingt from intensity data, e.g. via *.sca files:
• autoSHARP will internally run TRUNCATE to generate those amplitudes and anomalous differences from the input intensities
• the next release will contain a workaround to ensure that a different program (CTRUNCATE) will be used when encountering a faulty TRUNCATE version

You can determine the exact version of CCP4/TRUNCATE by running

% truncate -i

which should return something like

CCP4 software suite: library version 7.0.056
CCP4 software suite: patch level     7.0.056
Program:             truncate
