The Naibbe cipher

[ReneZ]

Note that the differences between RF1a and RF1b are very small, and for most purposes it does not matter which file one uses.

It only becomes important in case people want to compare results (to the last decimal place).

The transliteration at voynichese.com is quite different, though still easily good enough for most statistics.
It starts playing a role when trying to find individual words.

voynichese.com also lacks the entire rosettes page.
