Here are two one-liners for your .cshrc (FIXME: or should these lines go into .login or .profile?) :
alias sortlattices "egrep '^ .. [aomhtc]' IDXREF.LP | sort -k3n | head -12" alias scalefactors "egrep ' .... 0 ...... ....... .. ..... .... ... ...... ......' INTEGRATE.LP"
FIXME: what are these lines in bash syntax?
For the not-so-Unix-proficient-ones: sortlattices runs on IDXREF.LP the following commands:
- grep (for finding lines that are non-blank at two positions and have one out of the characters 'aomtc' later in the line)
- sorts these lines on the third column, numerically, ascending
- and prints the first 12 of these to the terminal
Example: dikay@turn29:-data/temp% sortlattices

(read Space group determination to find out what to do with these lines)
scalefactors finds those lines in INTEGRATE.LP which match a certain pattern of blanks and non-blanks. These are just the lines printed during the INTEGRATE step for each frame. It is very useful (e.g. to find shutter problems, or to "see" the crystal die from radiation damage) to run
scalefactors > frames.scales
and to plot the scale factors and mosaicity and beam divergence of each frame in gnuplot.
This can be done by
> gnuplot plot "frames.scales" using 1:3
or
> gnuplot plot "frames.scales" using 1:9
or
> gnuplot plot "frames.scales" using 1:10
It is useful to run gnuplot this way, because you can move the mouse over an outlier and see its coordinates (x=frame number) in the lower left corner of the plot window.
If you do have bad outliers (e.g. shutter didn't open), and decide that you for now simply want to remove those frames, then you could rename the frames (just append ".bad" to the name), and re-run XDS from the INTEGRATE step.
If you simply want the plots and glue them into your lab book, just run
gnuplot<<EOF set term png set grid set out 'scale.png' plot "frames.scales" using 1:3 set out 'divergence.png' plot "frames.scales" using 1:9 set out 'mosaicity.png' plot "frames.scales" using 1:10 EOF
to get File:Scale.png File:Divergence.png File:Mosaicity.png
