Not finding file using pop_loadbv function

Question

I'm using EEGLab and I'm having an issue. Indeed, I'm trying to load a vhdr files in order to preprocess datas. However, an error message occurs each time.

The error message goes as followed:

"Error using fopen Unable to find file. Ensure file exists and path is valid.

Error in readbvconf (line 59) fid = fopen(fullfile(pathname, filename), 'r');

Error in pop_loadbv (line 87) hdr = readbvconf(path, hdrfile);

Error in GlobalScript_ds_loc_hp (line 62) EEG = pop_loadbv('path', data_path, 'hdrfile',[subject_list{s} '.vhdr']);"

Here's the script below. Thanks !
