I try to assembled my illumina PE reads by using MaSuRCA assembler, but it aborted with the following error message:
$ ./assemble.sh

As far as I can see, the problem would have something to do with data trimming process. My raw reads was implemented adapter and quality trimming by using scythe and sickle, as discribed in the Assemblathon 2 paper. Then I ran the MaSuRCA.The 'FileParserError' problem was submitted at http://seqanswers.com/forums/showthread.php?t=33688 and http://www.biostars.org/p/73067/, but seems nobody found the solution.
Also, the similary error was arised in Soapdenovo 2 as 'Seg fault' as described at http://seqanswers.com/forums/showthr...290#post106290.I'm at a loss in finding the reason, and any guidance or suggestions would be very appreciated.
Best regards!
