Tutorial_Pipeline03.pl - Construct a UCSC genome browser trackhub
perl Tutorial_Pipeline03.pl [--out I<PATH>] [--baseurl -I<URL>] [--bigbeds -I<URL#URL>] [--bigwigs -I<URL,URL#URL>]
This script demonstrates UCSC genome browser trackhub construction with <Bio::ViennaNGS>.
The results of Tutalorial02_pipeline.pl are vizualized in UCSC, showing genomic region, annotation and expression level, which can be interpreted in conjunction to each other.
The result of this tutorial can be viewed by navigating your browser to here
This tutorial is based on the track_hub_constructor.pl script and the output from Tutorial02_pipeline.pl. While the option descriptions here are specific for the results from Tutorial02 the trackhub_hub_constructor.pl can be applied in the same manner to other datasets. The example call uses the bigwig and bedfiles available from our server. Example call: Tutorial_pipeline03.pl -o /home/user/public_html/hg19_trackHub -u http://nibiru.tbi.univie.ac.at/ViennaNGS/tutorial03/hg19_trackHub -b http://nibiru.tbi.univie.ac.at/ViennaNGS/tutorial03/hg19_highlyexpressed.pos.bb#http://nibiru.tbi.univie.ac.at/ViennaNGS/tutorial03/hg19_highlyexpressed.neg.bb -w http://nibiru.tbi.univie.ac.at/ViennaNGS/tutorial03/hg19_highlyexpressed.pos.bw,http://nibiru.tbi.univie.ac.at/ViennaNGS/tutorial03/hg19_highlyexpressed.neg.bw
For running this tutorial on your machine you will need a full installation of the Bio::ViennaNGS distribution, and result files obtained from tutorial02.pl, which can alternatively be downloaded from here):
For the UCSC genome browser to be able to visualize our trackhub it needs to be accessible via URL. This is the base URL you need to provide as commandline argument.
The resulting trackhub can only be read by the UCSC genome browser if it is accessible via URL. If you have no webspace for testing available you can use example output available from our webserver here.
Destination folder for the output Track Hub.
BaseURL used within the Track Hub. This URL will be included verbatim in the resulting Track Hub. It is crucial that this URl is valid, else the resulting Track Hub will be broken.
URLs pointing to big bed files to be included in the trackhub. Multiple URLs are separated by the character #.
URLs pointing to big wig files to be included in the trackhub. Multiple URLs are separated by the character #. It is possible to create a multiwig container by providing 2 URLs instead of one separated by comma character ,. E.g. http://foo.com/bar.bw,http://foo.com/bar2.bw#http://foo.com/bar3.bw yields a multi big wig container displaying bar as positive reads in green and bar2 as negative 3 red colored reads in the same track and additionally bar3 in an own track colored blue.
