I'm currently trying out ceres as an alternative to whisper in order to reduce the amount of diskspace being used (SAN space is getting expensive). Currently got quite a lot of data in the whisper format.

I've looked around and found the script to migrate the data files from whisper to ceres (convert-wsp-to-ceres) but when i do a test conversion the ceres file is missing the majority of the data points.  So it's gone from a whisper file with 20s of granularity over a 24hr period to a ceres file that has 3 data points spanning just 2 hours out of 24hrs :-S...

Any ideas what i'm doing wrong, am i missing some stops in the conversion process? can't find much information on it...
