txt2ldac is a python command line tool that takes a directory containing .txt files as input and generates three output files that can be used by the ldac or hlda implementations by David Blei (cf. [1] and [2]):

1. .dat – each line has the form: uniqueTerms term1:count term2:count … termN:count
2. .vocab – contains all unique words. The line number corresponds to the number used in the .dat file to represent the word
3. .dmap – lists all filenames. Line one lists the name of the document that is represented on line one in the .dat file. Used by David Blei's python script for tree generation for hlda results

run 'python text2ldac --help' for information about its usage.
