Yes. The following solution is due to Morten:
It is easy to display the reciprocal lattice. Here is an awk script that will create an ODL file for you. This one reads a TNT hkl file and outputs an ODL file. If your reflections are in X-PLOR format, replace the /HKL/ in line 2 with /INDE/. Save this in a file hkl2odl.awk:
BEGIN { print "begin recip" }
/HKL/ { print "dot",$2,$3,$4 }
END { print "end_object" }
Then:
awk -f hkl2odl.awk < input.hkl > output.odl.
If you want to add axes or set the colour, you have to edit those in manually; for example:
begin recip colour cyan move 0 0 0 line -30 0 0 move 0 0 0 line 30 0 0 move 0 0 0 line 0 30 0 move 0 0 0 line 0 30 0 move 0 0 0 line 0 0 30 colour magenta text 30 0 0 H=30 text 0 30 0 K=30 text 0 0 30 L=30 colour red dot -25 1 19 dot -25 1 20 ... end_object
NOTE: DATAMAN can also generate an ODL file from a reflection dataset for you.
