05 Jul 2004	Habibe Ngangoue	Hello Peter! There is a problem when running the command "jp2read" in a Matlab console : the filename must be specified (done easily) but what's the meaning of the second parameter of the function??You indicate in the comments that the filename only is necessary. But it appears that the variable "varargin" is mandatory for the rest of the process. Can you help me? Moreover, what do you mean by "You need to have the free available program "jasper" installed at your search path" ?? Regards Habibe
