run_ns_edit

PURPOSE ^

status = run_ns_edit(Epoch,Max_microv,Min_Chan,rawfname,Lo_Pass,Hi_Pass);

SYNOPSIS ^

function status = run_ns_edit(Epoch,Max_microv,Min_Chan,rawfname,Lo_Pass,Hi_Pass);

DESCRIPTION ^

 status = run_ns_edit(Epoch,Max_microv,Min_Chan,rawfname,Lo_Pass,Hi_Pass);

 Epoch = epoch length in seconds for artifact editing and spectral analysis
 Max_microv = maximum value in microvolts at a channel
 Min_Chan = minimum number of channelsin a good trial
 rawfname (optional) = NS Fragger filename
 Lo_Pass (optional) = Lo_Pass filtering frequency
 Hi_Pass (optional) = Hi_Pass filtering frequency
