Subset results for a large time window #2

Closed abyrd closed 8 years ago

abyrd commented 8 years ago

If we do the our RAPTOR searches on a 2-hour time window, our current intermediate results format allows rendering results for any smaller time window falling within the original window. ​ Additional comments from @mattwigway : We could potentially allow arbitrary time windows all day without much more information. Most of the size is in the paths, which scale less than linearly with additional minutes (because there is a fixed number of paths from A to B).​ We can also sample minutes, see a. owen’s work or even split the results up by time window (i.e. 8am-10am, 10am-12pm, 12pm-2pm, etc and just grab the ones needed for a particular analysis).
