mtz2sca is meant to guess the correct labels from the input mtz-file. Preference is set to I(+/-) over F(+/-) over F/DANO. These columns should be present if you used the default settings of the CCP4 User Interface. However, in case correct guessing fails or in case the user prefers other columns to be extracted, these can be provided on the command line. The following listing summarizes the options available in mtz2sca.

mtz2sca usage

     mtz2sca [OPTIONS] <mtzin> [<scaout>]
    
where
<mtzin>
filename of input mtz-file
<scaout>
filename of output sca-file
If <scaout> is ommitted, it is set to <mtzin> with its mtz-suffix replaced by sca, i.e. name.mtz to name.sca.

Without options, mtz2sca guesses the correct input data from the column types in the mtz-file. It searches for +/- intensity pairs (I+/I-), next for +/- amplitude pairs (F+/F-), and last for amplitude / amplitude difference pairs (F/DANO).

Possible options are:

-r name
root of labels. The mtz-file is searched for the four labels name(+), SIGname(+),name(-), SIGname(-)
-p name
Label for intensities or amplitudes for (hkl)
-P name
Label for standard deviation of p
-n name
Label for intensities or amplitudes for -(hkl)
-N name
Label for standard deviation of n
-h
print help message
-s
silent: supress output to standard out

Example

mtz2sca lyso_mos.mtz lyso.sca
converts a lysozyme data set lyso_mos.mtz processed with mosflm into the .sca-file lyso.sca.
mtz2sca lyso_mos.mtz
This is the same, but the output file name will be lyso_mos.sca.
