Hi,

I have some interest in start using the node "Python Filter", mostly because I need to use some mathematical functions of python (to calculate geodesical distances). The problem is that I haven't found any documentation about this node or how to use the brain python classes. Is there any place to look for this info? Tutorial, api, etc.?

Thanks for your help.

A Python Filter is a subset of the Python node where much of the processing has been done for you (reading the records, setting up the default metadata for the output. Take a look at the documentation on the Python node (core, under Miscellaneous), to see a lot of functionality available to you.

Additionally, if you want to look at some examples of Python nodes, open up core itself in BRE, and you will see a bunch of the nodes in it are actually implemented in Python, and you can see how they work.

Cheers
Rich
