Calibration and validation in ANN model

I have 3348 data, of which I want I want to use 2232 as calibration data to validate in 1116 data in ANN model. I earlier used 70% training ratio, 15% as validation ratio and 15% as test ratio.

% net.divideParam.trainRatio = 60; % net.divideParam.valRatio = 20; % net.divideParam.testRatio = 20; [net,tr] = train(net,Inputs,targets); nntraintool

Is this is the right way or is there any way? Really appreciated your time and help.
