hlmerge

This utility takes as input a single molecule file (SD or OEB) or list file containing one or more molecules files. It will re-rank these input files by a user-defined SD tag. The most common use is to create a single hitlist after running ROCS on the separate files created by chunker.

Command Line Parameters

Required parameters:

-in <filename>

Name of input file to rank, or the name of a list file (.lst or .list) containing a collection of files to rank.

-out <filename>

Output structure file for sorted hits. Formats other than SDF or OEB will lose the SD tag data.

-rankby <SD tag>

SD tag containing a score (that can be converted to a floating point value) to use as the score to rank with.

Optional parameters:

-besthits N

Number of hits to keep. [ default = 500 ]

-biggerisbetter

By default, hits are ranked with higher scores meaning better results. To rank by a score where the smaller value is better, use -biggerisbetter false. [ default = true ]

Examples

Assuming a set of ROCS results for the previous chunker example are in a file called bar.list:

bar0000001_hits_01.sdf
bar0000002_hits_01.sdf
bar0000003_hits_01.sdf
bar0000004_hits_01.sdf
bar0000005_hits_01.sdf

To merge these, rank by Tanimoto Combo and then keep the top 200.
