CMS WIS to txt for spectragen.m

function[] = CMS_WIS_to_txt_for_spectragen() %This function creates the .txt file used in the spectra generator of % CMS Wave. It prompts the user to select all the desired WIS output files, % specify the depth of the station, and whether or not to average the data % series. The data and user inputs are manipulated into the format used by % CMS Wave file import for spectra generation. Currently the output file % is saved in the active directory of matlab. This can be changed by % adding in desired destination in the definition of variable 'outfile' on % line 56. % % % Created: 26 JAN 2012 % Author: Kevin Hodgens, USACE, SAJ, kevin.c.hodgens@usace.army.mil % Modified: DD MMM YYYY by _____ % Notes: changes include....n/a
