THE LOG FILE

INTRODUCTION

When the program ROTGEN is run, a log file is normally written. By default this is named 'rotgen.log' but a user chosen file name may be selected via a command line option or by setting an environment variable as described elsewhere in the documentation.

CONTENTS OF THE LOG FILE

When a new parameters file is read in, the values of the keyworded parameters are written to the log file.

When a data analysis has been carried out, then any keyworded parameter values, which have been changed since reading in a new parameters file or since the previous analysis, are written to the log file. Three analyses tables are output in a form which may be accessed by the CCP4 'xloggraph' program if desired. These are for unique data coverage, acentric pairs coverage and reflection multiplicity. All are shown as functions of resolution in 10 resolution bins. These analyses exclude spatially overlapped reflections.

Analogous analyses including spatially overlapped reflections will only be written to the log file if this was specifically requested when examining the analysis results in ROTGEN.

The results of any strategy calculations and any related analyses are also written to the log file together with details of any strategy solution accepted.

When the program is terminated, the current values of the keyworded parameters are written to the log file.

The use of the 'Rotation Simulations' option does not result in any additional log file output.

KEY TO ANALYSIS TABLES

This section indicates the meanings of the items found in the analysis tables:

Bin no.      Resolution bin number (1 to 10)
s_ave        Average value of 4sin**2(theta)/lambda**2 in the bin
d_min        Highest resolution (minimum d-spacing) for the bin
reflns.      Reflections
f            Fully recorded reflections only
f,p=2        Fully recorded reflections + partials on 2 images
f,p<=3       Fully recorded reflections + partials on up to 3 images
f,p<=nwmax   Fully recorded reflections + partials on up to 'nwmax' images
nwmax        Partials limit parameter used in prediction (>=3)
