The word frequency files '*/*/*/gud.wfr' are available at the [https://www.ic.unicamp.br/~stolfi/EXPORT/projects/voynich/Notes/tr-stats/dat/ UNICAMP website].  The original annotated full texts, before truncation/filtering, are in the companion files */*/org/main.src.  The truncated/filtered texts -- one word per line, without punctuation -- are in */*/*/gud.tlw.
