two questions about data analysis of .was .wds filePosted by jyp at July 08. 2012
i have storm version 114 and quickwave in my computer. i am doing data analysis about the was and wds files.
please see questions in attached file, thank you very much.

Q1. I want to export the process data as following, but only the .whr is exported, other files are failed. The question is: how to export the other files?
A: My copy of Storm 1.14 give of the wanted files. Have you rebooted the computer after installation of Storm?
Q2: I got the .wap .was .wds file from the quickwave. I guess the energy spectrum figure by storm is plotted from the data of .was file, and direction spectrum contour is plotted from data of .wds
file.The question is :For one time of observation, the max from the contour figure is 0.0062, but the max of array in the .wds file is 1.16. The max from the figure and data file is rather different. I am puzzled.
A: The plot at the top in your attachment labelled energy density should be the .was file. Plot number 2 labelled direction should be the .wdr file. The plot at the bottom labelled AST spectrum is the same as the .wds file, but scaled differently. The plot is scaled such that the integral from 0 to 360 deg for one frequency is 1. This is done to have the wanted dynamics. At first we tried to implement this to the .wds file as well, but the size of this file became enormous because of the data type needed and ASCII representation.
Hopefully this will help you out. If there still is questions, please tell me.
