Error using preparets (line 110) Targets and inputs have different numbers of timesteps.

I am using NARXNET to forecast wind speed using 25 different metrological data. Getting error as "Error using preparets (line 110) Targets and inputs have different numbers of timesteps."

my data N1 is 186 X 26 matrix with 26th column as target. [N1,header]=xlsread('DATA_ADL.xlsx',6); N1=N1'; %% in=N1(1:186,1:25); out=N1(1:186,26:26); % inputSeries= con2seq(in); targetSeries= con2seq(out); % trainFcn = 'trainlm'; % Levenberg-Marquardt backpropagation.

inputDelays = 1:10; feedbackDelays = 1:8; hiddenLayerSize = [5 12];

net = narxnet(inputDelays,feedbackDelays,hiddenLayerSize,'open',trainFcn);

net.layers{1}.transferFcn = 'radbasn'; net.layers{2}.transferFcn = 'tansig'; net.layers{3}.transferFcn = 'tansig';

net.inputs{1}.processFcns = {'mapminmax','mapstd'}; net.inputs{2}.processFcns = {'mapminmax','mapstd'};

[inputs,inputStates,layerStates,targets] = preparets(net,inputSeries,targetSeries);

Can anyone help? what i am doing wrong on this?

Have you checked size of inputSeries and targetSeries

they must be [1 26] and [1 1] respectively.
