Update: 9 Aug 2006 - New Movies

Post by albutterworth » Wed Aug 09, 2006 5:29 pm

Tile I007 uploaded last night and the movies were made available this morning [9Aug06]

Tile I033 is uploaded and available for searching [10Aug06]


Many of you following the project since May will already know that scanning thousands of fields of view over the aerogel and producing focus movies is a time consuming task, sometimes requiring re-scans of the same tile.

Data Timelines
1) It takes a day to scan each tile (in Houston) producing about 4000 movies
2) About once a week, the data are sent to Berkeley where we process the raw, uncompressed movies to produce our focus movies for the virtual microscope (VM). That also takes about a day per tile.
3) We then run an automated quality-checking program to decide if we need to rescan the entire tile

4) The focus movies are uploaded to Amazon S3 servers and entered into our database. This takes about half a day.
5) Finally, we update the VM to include the new movies. This step is instant.


Uploads and the launch
We had our fair share of glitches launching Stardust@home last week. You fix one thing and something else gets affected! We were not able to upload any new movies while making some major back-end changes.

Uploads have now resumed and I regularly update 'Picture Perfect' to show our progress. Tiles in green are being searched!

Best of luck to everyone. Happy Dusting
