hi, its definitely possible to view large datasets on flash. Flex charts support around 4k data points.
You'll have to develop a custom flex component to implement gene viewer. Am using a loose term "component", it will be a project in itself. Looking at first screenshot, the gene sequence is shown as bars. Practically speaking, you will show max ~ 1000 items on screen (as screen resolution may be be 1078). App doesn't need to cache entire gene dataset in memory, that will consume so much memory and make browser unresponsive. Instead fetch the required data based on two factors - range (e.g. sequence 10k - 20k) and zoom (granular like second image or high level like first image). Your server should be very responsive (which requires good db design). Choose a effective protocol to send data. E.g. don't use xml as it is verbose. Instead pack data as char/byte arrays. Use flex to layout high level stuff and use flash graphics to draw the bars, etc. Am curious where did u get these snapshots from? is that an existing software? hope this helps. regards, Raj On Tue, Feb 22, 2011 at 11:39 AM, Arulmurugan <[email protected]>wrote: > Hi, > > We need to develop a genome viewer. > > The viewer has three parts. > > One part shows the entire genome sequence.
