Hi Jeff and Devan, Right now until data is loaded, a data object doesn't know its own size. (This changes in the geometry refactor.) However, this should get you what you want: reg.quantities["TotalQuantity"]("Ones") A bit obtuse, but will give you a cell count. (FWIW, you can get all of the data that comes from stats/print_stats yourself by looking at level_stats on the hierarchy object.) -Matt On Thu, Jul 26, 2012 at 6:32 PM, j s oishi <jsoishi@gmail.com> wrote:

Hi Britton,

Thanks for the message. Unfortunately, this needs to be within the api, in an analysis module, without loading any data. It also needs to be done on a particular AMRRegion that gets fed in to the (new) module.

thanks,

Hi all,

My name is Devan Conroy and I am working at SLAC as a summer intern in the SULI program with Jeff Oishi. I am trying to figure out how to count the number of cells in the grid when loading in data. I tried using (len(DataIn)), but got the error: object of type 'AMRRegion' has no len().

Any suggestions?

Thank you, Devan Conroy
