How to access wavelength using hyperReadAvirisRfl function?

Dear Sir,

I could able to access the reflectance value by executing the following coding: a=hyperReadAvirisRfl('f970619t01p02_r02_sc02.a.rfl', [1 100], [1 614], [1 224]); The above line executed successfully and returned the reflectance values.

But i need the corresponding wavelength for these reflectance value. According to my knowledge, the function "hyperReadAvirisRfl",should return both reflectance and wavelength. So, i tried by adding one more variable to receive the wavelength values as follows: [a b]=hyperReadAvirisRfl('f970619t01p02_r02_sc02.a.rfl', [1 100], [1 614], [1 224]);

But it gives error as follows: ??? Error using ==> fgetl at 44 Invalid file identifier. Use fopen to generate a valid file identifier. Error in ==> hyperReadAvirisSpc at 19 txt = fgetl(fid); Error in ==> hyperReadAvirisRfl at 56 wavelengths_nm = hyperReadAvirisSpc('f970619t01p02_r02.a.spc');

Kindly help me out Sir.
