GBrowse/GMap Mashup

The purpose of this code is to create a mash up of GBrowse data and Google Maps that displays diversity data of a feature in the locations that they were sampled.

Code

This code was started as a modification of the gbrowse_details script.

Template Toolkit is used to generate the html for the page. The template is encased after the __DATA__ token.

Usage

GMap API Key

To use this, a GMap API key must be supplied in the GBrowse configuration file. As of writing, keys are freely available from Google at http://code.google.com/apis/maps/.

The configuration option name is "gmap_api_key" and is specified like the following:

gmap_api_key = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

Balloon Configuration

To place the mashup in a balloon, simply add something like the following to the track configuration.

balloon click = http://localhost/cgi-bin/gbrowse_gmap/yeast_chr1?ref=$ref;start=$start;end=$end;name=$name;class=$class;db_id=general

The "yeast_chr1" portion should be replaced with the coorect data source.

Also, "localhost" should be changed to your url. A relative url may not work because Google ties the api key to a URL.

TODO

This is currently a work in progress.

• Import longitude and latitude data

• Use longitude and latitude to place pins

• Modify the pins to be graphical representations of the population at that point.

• Determine appropriate size, zoom level and center of the map on load.
