%%%%find the start and end time%%%%%

%%%%select the pressure channel in instrument#####
pressurechannel=stFile.data(5,:);

%%%%create variable with the start time updated
pressurechannelStartTime=stFile.dStart(1,:)

%%%%convert the data in MATLAB variable to .SAC format using MKSAC
mksac('s3mendo_goldfish_s03_test.sac',pressurechannel,pressurechannelStartTime,'DELTA',(1/62.5),'KSTNM','s3mendo','KCMPNM','SHZ');

%%s3mendo_goldfish_s03_test.sac -> output file in SAC format
%%%DELTA = time increment 
%%%KSTNM = station name
%%%KCMPNM = channel
