Answers.Body: <p>While the selective-alignment algorithm that is part of salmon is designed for short reads, salmon also supports quantification via alignments in a SAM / BAM file (aligned by other tools).  You have to be somewhat careful about setting the proper command line flags, but nonetheless, the quantification should work fine.  You can, for example, find a pipeline that uses minimap2 for alignment followed by salmon for quantification of long reads <a href="https://github.com/nanoporetech/pipeline-transcriptome-de" rel="nofollow noreferrer">here</a>.</p>

Answers.Body: <p>Stringtie now does long reads too. We've found flair to be quite difficult to install and to crash often. That said, stringtie isn't very good about showing you its working (e.g. I have no idea how to get it to give the assembly it uses to figure out all the isoforms). Its values for TPM/FPKM also seem a little weird, in that they're perfectly correlated with each other, and for transcripts they're perfectly correlated with coverage too.</p>

  <p>TALON is another tool that does isoform assembly. I'm not sure whether it does quantification though.
