Removing element from two vectors by using ginput

Hello, i am using ginput to manually remove a peak from my plot. I have the locations of my peaks and their amplitudes in handles.R_t and handles.R_amp respectively. The following doesnt seem to work and returns empty row and columns as the maximum that I find around the neighbourhood of the click is slightly different from the value I have stored in the handles.R_t. Any help/solution or any clever ideas to avoid this problem?

        [x_peak1,y_peak,button] = ginput(1);
        [yy xx] = max(handles.bpf((round(x_peak1*handles.srate))-50:(round(x_peak1*handles.srate))+40));
        y_peak = yy;
        x_peak = xx/handles.srate + x_peak1 - 50/handles.srate;  
        temp1 = handles.R_t;
        temp2 = handles.R_amp';
        handles.R_t = zeros(1,length(temp1)-1);
        handles.R_amp = zeros(1,length(temp2)-1);
        viBelow = (temp1<x_peak);
        viAbove = (temp1>x_peak);
        newa = [temp1(viBelow) temp1(viAbove)]';
        [row,column] = find(temp1 == x_peak);
        Anew = zeros(1,length(temp2)-1);
        Anew = temp2([1:row-1, row+1:end]);
        handles.R_t = newa';
        handles.R_amp = Anew;
