IGB QuickLoad is a very simple data integration and sharing system IGB uses to combine data from multiple sites. If you have big data sets to share, you can add them to a QuickLoad section of your lab Web site and then publish the URL. IGB users can then enter the URL into IGB and see your data alongside other data sets (gene models, ESTs, TDNA insertions, RNASeq, etc) provided by other groups. You can also password protect the data if you want to keep it private prior to publication. So far as I know, none of the other desktop genome browsers support this; this is unique to IGB. However, they may adopt it as well – it is very simple and requires no specialized software.
If you are interested in trying this in your lab, the IGB team would be glad to provide advice and help, as this will help us improve the documentation and give us ideas for new features. More information about QuickLoad is here: http://wiki.transvar.org/confluence/x/0YIHAQ.
