Good reference-based genome assembly tool

SPAdes has "trusted contigs" option, but it's not really reference-based assembly. I know velvet has that option, but I don't find it user-friendly. Is there any other reliable tool for reference-based assembly.

reference based transcriptome or genome assembly?

Reference based genome assembly. Have edited the title. Thanks

not sure what kind of data you are working with (short read? long read?) but if memory serves I thought that Flye assembler could also do (some sort of) reference based.

Illumina around 300bp

For small genomes (< 40 Mb), MIRA works very well. Beware that it can do a hybrid assembly using data from different technologies, excluding PacBio and Nanopore.

Actually, MIRA can use PacBio and Nanopore reads, provided:

  • the reads have been error-corrected (either PacBio circular consensus, or Illumina-correction for both PacBio and Nanopore),
  • in case the reads are really long, they need do be chopped to a 32kb maximum length, probably even less, so that memory usage doesn't explode.

MIRA is a great assembler, but overly complex, and development apparently stopped at 2016, so it didn't catch up with the latest sequencing technologies improvements.
