APS Results File Variable Names

Post by jplayle »

When calling the function get_variables() the list of variables relevant to the results file is returned. Each variable has its display name for Vista and the 'aps_varname' which is its name within the results file.

The problem is, the 'aps_varname' that is listed for the variables 'Operative temperature', 'Degrees > Max. adaptive temp.' and 'Daily weighted exceedence' shows up as 'Room air temperature&Temperature [w]' which not only is duplicated but also does not return the desired variable when used to call the get_results() function on the results file.

Does anyone know what the correct 'aps_varname' is to return data about these variables from a results file? Any help greatly appreciated!

There are a few results that can't currently be read using the Python API (these variables are derived on demand by Vista - the variable you indicate is unfortunately one of them).

We are working on adding support for these variables, and our next release will have the ability to read them. When the work is completed, the API for get_room_results will be able to take Display Name or APS variable name (due to the ambiguity in variable naming). The change should be backwards compatible with existing scripts.

Until that update is released, unfortunately I don't know of any other way of reading that data using the Python API.
