I prefer to identify gene models in MAKER (GFF3) and use those to train both SNAP and Augustus. Here is a previous post on the topic —> <a href="https://groups.google.com/forum/#!searchin/maker-devel/augustus/maker-devel/FWMSTdqWQqI/lC3miQtiCpwJ" class="">https://groups.google.com/forum/#!searchin/maker-devel/augustus/maker-devel/FWMSTdqWQqI/lC3miQtiCpwJ</a><div class=""><div class=""><br class=""></div><div class="">In the end you need to look at the SNAP and Augustus models together with evidence alignments in a genome browser (like desktop Apollo). When everything is trained well, both SNAP and Augustus models will look like each other and both seem to look like the evidence alignments.</div><div class=""><br class=""></div><div class="">Thanks,</div><div class="">Carson</div><div class=""><br class=""><div class=""><br class=""></div><div class=""><br class=""><div><blockquote type="cite" class=""><div class="">On Feb 4, 2016, at 5:52 PM, hcma <<a href="mailto:hcma@uci.edu" class="">hcma@uci.edu</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div class="">Hi,<br class=""><br class="">I have a genome sequence and Trinity assembly for a new species and I am wondering what are the best steps to take when using MAKER?<br class=""><br class="">1.
