Unable to Save Multiple plot images

Got struck with this can u please help ..

        xyloObj = mmreader('Movie.avi');
         nFrames = xyloObj.NumberOfFrames;   

        folder = fullfile('path');
  movieFullFileName = fullfile(folder, 'Movie.avi');

[folder, baseFileName, extentions] = fileparts(movieFullFileName );
  folder = pwd; 
    outputFolder = sprintf('%s/Movie Frames from %s', folder, baseFileName);
  mkdir(outputFolder);

for k=1:nFrames
      mov(k).cdata = read(xyloObj, k);
        Frame = read(xyloObj, k);
    caluclating Fourier transform of Each Frame 
    taking Frequency plot of each frame 
    freqz2(Frame,[32 32]);%Frequency plot of the FFT frame
    saveas(gcf,'freqplot ','png');%saving freq plot
    pp= imread('freqplot','png'); %reading it 

      outputBaseFileName= sprintf('freqplot%d.png',k);
          outputFullFileName =   fullfile(outputFolder,outputBaseFileName);

             imwrite(pp, outputFullFileName,'png');
      end;
It is storing freqzplots with the different names like freqplot1,freqplot2,freqplot3,......so on 
But the same figure is present in each plot but with different names ..
How to get the correct plot figure of the frames

saveas(gcf, 'freqplot ', 'png');%saving freq plot
pp= imread('freqplot', 'png'); %reading it

You save the file with a trailing space, but read another file without this space.

BTW. I do not see the reason for SAVEAS->IMREAD->IMWRITE You could save it under the correct path directly.

how to save the obtained frequency plot directly in the folder..

[Jan]

outputBaseFileName = sprintf('freqplot%d.png',k);

outputFullFileName = fullfile(outputFolder, outputBaseFileName);

saveas(gcf, outputFullFileName, 'png');

thanks..this is working good
