Error using VideoReader/init (line 607) The filename specified was not found in the MATLAB path. Any ideas how to fix that error?

You passed in a file name that is not the name of any file in your current directory or any directory on the path. In other words, you asked it to read a non-existing file.

but the video is in the directory! i cant find why there is an error

We need to see your code.

[abbxucy11]

 video =[handles.FilePath handles.FileName]; 
  axes(handles.axesRoiVideo);        

 %create a  matrix to save the array of croped images

 img =  frame2im(VideoReader(video,1))

I ran the code with breakpoints and it's okay , the video variable is recognized by the first command but there's an error at the command VideoReader

%when you use uigetfile(), the path that is returned might not end in a folder separator. Use fullfile() to be safe.

filename = fullfile(handles.FilePath, handles.FileName);
if ~exist(filename, 'file')
  error('Video file "%s" does not exist', filename);
end

try
  videoobj = VideoReader(filename);
catch
  error('File "%s" cannot be read as a video', filename);
end

img = readFrame(videoobj);   %no frame2im !

If you have an old enough version of MATLAB then you will instead need

img = read(videoobj, 1);     %no frame2im
