v5 v6 25 25 * **Mapping** 26 26 * Use [[http://tophat.cbcb.umd.edu/manual.html|TopHat]] (or another spliced mapper) to map short reads to genome of choice with default settings except 27 * Selecting a value for --segment-length equal to half of the read length can greatly help spliced mapping (across an intron) [''ex: For 40-nt reads, use '--segment-length 20' ''] 27 * Selecting a value for --segment-length equal to half of the read length can greatly help spliced mapping (across an intron) [''ex: For 40-nt reads, use '--segment-length 20' '']. For longer reads (>~45 bases), the default value (25) can be used. 28 28 * Supplying a GTF file describing gene models to TopHat can provide better mapping of some spliced reads. 29 29
