Text-Tidx version 0.91 ====================== Text:Tidx allows you to index any text file using key fields start-stop coordinates, and, later, use that index for binary-search lookups into the file, even though there is a range of responses. This was written because it was, for me significantly faster, for very large files (>100k rows) and many searches ( > 10k), then entering all of the information into a database and doing range querys, even faster than SQLITE's rtree extension, or the "tabix" program both of which are do similar things and do them rather well. Although it was designed for chromosome, stop, start indexing, it is not genome specific, and can index any delimited text file. Indexes are loaded into RAM. If you only have a few lookups to do perl instance, this is expensive, and a database will be faster. INSTALLATION To install this module type the following: perl Makefile.PL make make test make install DEPENDENCIES This module includes google's sparsehash, some code from ea-utils, as well as the tidx-lib source because they're small, however, they can be replaced with newer versions of those libraries if desired.
