Do not start the GUI by calling the FIG file, but start the corresponding M-file.

Answer 2

hey i am very new to this matlab, with biology background. its really tough for me to understand thing but i tried with what u said.

Error using fileparts (line 34) Input must be a row vector of characters.

Error in openfig (line 53) [path, name, ext] = fileparts(filename);

this is the error i get when i go through opening m-file

what should be done next
