%function [membranPotAVG]=avgPerFrame ...
%         (membranePot,ttls_ms)
%builds the average membrane potential between frames for the white noise
% -> same principle for frozen frames
% INPUT:        membranePot -> membrane Potential
%               ttls_ms -> pulses in ms
% OUTPUT:       membranPotAVG -> average membrane potential per frames

membranPotAVG=zeros(1,length(ttls_ms)-1);%preallocate

%make the average membrane potential between two stimulus frames
for jj=1:length(ttls_ms)-1 
    membranPotAVG(jj)=mean(membranePot(ttls_ms(jj) ...
        :(ttls_ms(jj+1)-1)));%detail: -1ms because the next ms is already the start of the new stimulus frame
