Hello. Regarding the Conservation scores, it is important to note that there are three types of Conservation scores in the Conservation track: PhastCons, PhyloP and Conserved Elements. When you have questions regarding methods used to generate scores or other data in a track, it is always a good practice to read the track description pages. The Conservation description page is at http://genome.ucsc.edu/cgi-bin/hgTrackUi?db=hg19&g=cons46way and the UCSF Brain Methyl description page is at http://genome.ucsc.edu/cgi-bin/hgTrackUi?db=hg19&g=ucsfBrainMethyl. For your questions regarding the Conservation scoring, you will find the answers by reading through the Description section and the Methods section.
You can always find the range of values for a track by viewing the configuration options. For example, if you are viewing the UCSF Brain Methyl track in the Browser, you can right-click on any subtrack and select "Configure UCSF Brain Methyl track set". If you are interested in the data range for the Raw Signal subtracks, click the Raw Signal link which will open those track controls. Notice that next to "Vertical viewing range", you see "(range: 0 to 1000)". You can do this with any track to obtain the ranges (though the options for different subtrack types will be slightly different). Please contact us again at [email protected] if you have any further questions. --- Steve Heitner UCSC Genome Bioinformatics Group -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of shasha Sent: Wednesday, April 25, 2012 1:05 PM To: [email protected] Subject: [Genome] Several questions about how to use the Genome Browser. Dear Sir/Madam I wish you are having a wonderful day. I have a couple of questions about the Genome Table Browser to consult you. As to the Conservation track. I just wondering that what is the range of the conservation score? Why some scores could be negative? If the score is negative, what does it mean? As to the UCSF Brain Methyl track, what is the range of the Signal value? Thank you for your kind help. Best wishes. _______________________________________________ Genome maillist - [email protected] https://lists.soe.ucsc.edu/mailman/listinfo/genome _______________________________________________ Genome maillist - [email protected] https://lists.soe.ucsc.edu/mailman/listinfo/genome
