Hi, I'm trying to assemble Illumina paired sequence which is at least 15x deep to the Arabidopsis genome (TAIR 10 version) using Map with Bowtie for Illumina (version 1.1.2) but try as I might with changing all the parameters in different ways to reduce stringency I am still getting a lot of gaps in the assembly (probably about 10% missing). What settings would you advise I focus on to try and improve the situation? Many thanks in advance! Marc. *** Professor Marc R.
