This tools aligns single-end reads to publicly available genomes or transcriptomes. If you would like other reference genomes to be added, please contact us. If you would like to align reads against your own datasets, please use the tool "Bowtie against own genomes"
Bowtie aligns reads to a reference sequence such as genome or transcriptome. There are two modes: mismatches are considered either throughout the read, or only in the user-defined left part of the read. In the latter case also quality values are taken into account. The Chipster implementation Results are sorted and indexed bam files, which are ready for viewing in the Chipster genome browser. Note that this Bowtie tool uses public genomes provided by Chipster. If you would like to align reads against your own datasets, please use the tool "Bowtie against own genomes".
After retrieving the promoter sequences, they are submitted to the Weeder program that finds common motifs (putative transcription factor binding sites). Weeder can find motifs of two different sizes. The sizes are the same for all species. The length of the common motif and the number of allowed mismatches in the motifs varies with the setting:
Length Mismatches Small 6 1 8 2 Medium 10 3
In addition, the user can define:
Tool returns a specified number of common motifs written to an HTML file. These can then be further analyzed to verify whether they are known transcription factor binding sites.
