I am having trouble with plotting the cells from a cell array. The array has 158 cells of varying sizes and i wish to plot them on a raster plot with 8 different graphs. So far I have :

for i = 1:8
    indDir1 = find(direction==1);
    indDir2 = find(direction==2);
    indDir3 = find(direction==3);
    indDir4 = find(direction==4);
    indDir5 = find(direction==5);
    indDir6 = find(direction==6);
    indDir7 = find(direction==7);
    indDir8 = find(direction==8);
    indDir = [indDir1;indDir2;indDir3;indDir4;indDir5;indDir6;indDir7;indDir8];
    numTrials = length(indDir);
    subplot(3,3,graph(i));hold on;  % this is all for the subplots..here is not the issue
    for i = 1: size(instruction)
      spiketimes{i} = num2cell(neuron1.times(neuron1.times(:,1) >= instruction1sb(i) & 
  neuron1.times(:,1) < instruction1sa(i)))
    end;                             % This is how i created the cell array with 158 cells for each trial
    for j = [1:numTrials];
      n = length(spiketimes);
          % Here is where I have no idea how to plot these cells
      plot([spiketimes ;spiketimes ], [ones(n,1)*j-1; ones(n,1)*j]);
    end;
end;

Please help!!!

Shane - if you step through the code (using the debugger) what can you tell us about spiketeimes? How many elements are in this array - 158? What are you attempting to do with

plot([spiketimes ;spiketimes ], [ones(n,1)*j-1; ones(n,1)*j]);

I don't understand why you are concatenating spiketimes with itself and then repeating this for each trial. What are you attempting to do with the ones(n,1)*j-1? What does this mean?

I have moved forward with this:

for j = 1:158

n = length(spiketimes);

ix=cellfun(@isempty,spiketimes);

spiketimes(ix)={0} ;

for ii = [4,16,20,32,36,89,111,119,129,156] % Here I turned NaN values to 0 then into an empty cell

a = spiketimes {ii}; if a==0 spiketimes{ii} = cell{1};

end

%n = length(results(j,:));

%result(j) = spiketimes{j}; % not sure ifll end up needing these

line([spiketimes{j,1} ; spiketimes{j,1}],[ones(1,n)*j-1;ones(1,n)*j],'k-');

end; end;

Error using line Conversion to double from cell is not possible. % This is the error im currently getting

PLease...anyone..I would really appreciate the help. I need to be able to plot this. Eventually im going to have to assign these plots for different direction but for now im just trying to get past plotting the cells
