I'm using OpenCV 3.2. I need to save a trained ANN_MLP network, but it needs to be saved in the same file as other serialised data from the application (the api specifies only one set-up file), so I need a save() method that appends to existing data in a file.

Is there a way to save ANN_MLP by appending to an existing file and then read it back again?

Failing that, is is possible to "train" a network by setting the weight matrices, instead of using train() or load()? This would enable me to simply write/read the matrices that describe the network.

Thank you, berak. For info, in the simple case of writing and reading, this works: cv::FileStorage fs; fs.open(

I have solved the second part of this question: it is possible to create a working network by copying the matrices. The
