The ixIxx utility has a default of 31 characters for words. If you build an input.txt
with longer words, such as very long accessions, you neeed to add the option -maxWordLength=N
to override the default and expand it to the size you are using for the longest words in your index.
If you want to use your Trix index in a track hub, see the searchTrix setting in the
Track Database Definition Document.
