MATLAB: Reading image and pulling, RGB and pixel number from GIF format image

gifimage analysisimage processingImage Processing Toolbox

Hello,
I am working on a code to pull the RGB values from a gif frame by frame, then load them into a file in a specific format to load into a LED lighting array. I cannot seem to get it to label the LED numbers correctly, or how I want them numbered. When running the following code through matlab it seems to label the LED numbers in a different order. Here is the code I am using.
sourceimage = '/Users/tapotter/anime/leda11.gif'; %Pull file to load
numframes = numel(imfinfo(sourceimage)); %Pull the number of frames
fid = fopen('FastLEDAnimation.txt', 'a+'); 
for frame = 1:numframes %Go through each frame of the gif
  fprintf('Frame:  %d Complete', frame); %Post to the console when each frame is complete
  [img, map] = imread(sourceimage, frame); % Open the image and create the map
  rgbimg = im2uint8(ind2rgb(img, map)); %turn the index into  unit8 rgb format
  crgb = reshape(permute(rgbimg, [3, 1, 2]), 3, []);  %makes a 3xnumpixels array
  framedelay = imfinfo(sourceimage); %Pulls the frame delay from imfinfo
  fdelay = framedelay.DelayTime; 
  pixcrgb = [1:size(crgb, 2); crgb];  %Sets up the readout to include what pixel its on(not working as I thought)
  fprintf(fid, 'leds[%d].setRGB(%d, %d, %d);\n', crgb);
  fprintf(fid, '\n FastLED.delay(%d)\n', fdelay);
end
fclose(fid);
Here is a sample of the output I am getting,
leds[0].setRGB(0, 0, 0);
leds[0].setRGB(0, 18, 20);
leds[20].setRGB(8, 8, 9);
leds[20].setRGB(34, 36, 20);
leds[34].setRGB(36, 20, 40);
leds[47].setRGB(33, 65, 70);
leds[22].setRGB(52, 54, 33);
leds[65].setRGB(70, 12, 70);
leds[80].setRGB(33, 65, 70);
It should be reading
    leds[0].setRGB(0, 0, 0);
    leds[1].setRGB(0, 18, 20);
    leds[2].setRGB(8, 8, 9);
    leds[3].setRGB(34, 36, 20);
When I look at the data that is generated for the "pixcrgb" data I can see it is correct, at least number going through the number of pixels in the image. I am attaching a screen shot of the data I am seeing through matlab. Does anyone know how I might get the required number from pixcrgb? Example at the top it is labeling the 1, 2, 3, 4, 5, followed by the RGB values. Next just to make sure I understand how the gif or image is being read, is it in this format?
//     0 >  1 >  2 >  3 >  4
//                         |
//     .----<----<----<----'
//     |
//     5 >  6 >  7 >  8 >  9
//                         |
//     .----<----<----<----'
//     |
//    10 > 11 > 12 > 13 > 14
//                         |
//     .----<----<----<----'
//     |
//    15 > 16 > 17 > 18 > 19

Change
fprintf(fid, 'leds[%d].setRGB(%d, %d, %d);\n', crgb);
to:
fprintf(fid, 'leds[%d].setRGB(%d, %d, %d);\n', pixcrgb);
Otherwise pixcrgb = [1:size(crgb, 2); crgb]; is not considered anywhere.
