HI I wrote a program that use to work (swear to god) and has stopped from working. this code takes a series of BMPs and convert them into avi file. this is the code:

path4avi='C:/FadeOutMask/'; %dont forget the '/' in the end of the path
pathOfFrames='C:/FadeOutMask/';
NumberOfFiles=1;
NumberOfFrames=10;

%1:1:(NumberOfFiles)
for i=0:1:(NumberOfFiles-1)
FileName=strcat(path4avi,'FadeMaskAsael',int2str(i),'.avi') %the generated file
aviobj = avifile(FileName,'compression','None'); 
aviobj.fps=10;

    for j=0:1:(NumberOfFrames-1)
    Frame=strcat(pathOfFrames,'MaskFade',int2str(i*10+j),'.bmp') %not a good name for thedirectory
    [Fa,map]=imread(Frame);
    imshow(Fa,map);
    F=getframe();
    aviobj=addframe(aviobj,F)
    end
aviobj=close(aviobj);
end    

And this is the error I get:

??? Error using ==> checkDisplayRange at 22
HIGH must be greater than LOW.

Error in ==> imageDisplayValidateParams at 57
common_args.DisplayRange = checkDisplayRange(common_args.DisplayRange,mfilename);

Error in ==> imageDisplayParseInputs at 79
common_args = imageDisplayValidateParams(common_args);

Error in ==> imshow at 199
  [common_args,specific_args] = ...

Error in ==> ConverterDosenWorkd at 19
    imshow(Fa,map);

for some reason I cant put it as code segments. sorry

thank you
