Hi Rakesh,

You can skip the lines above the data while reading the txt file. The following code worked for me for extracting the node displacement values.

fileID = fopen('Onefwp.txt');
nodes = cell2mat(textscan(fileID,'%f %f %f %f %f','HeaderLines',11096));
fclose(fileID);

If you run the above code, the nodes variable will be a 4961x5 matrix, with 1st column representing the node id and 4th and 5th column representing the displacement values.

Hope this helps!
