WinError2 - File cannot be found error when trying to run selective_search on Windows

[cfstiff]

I'm trying to run the selective_search code. I was able to get demo.m to run, but cannot run the python version of the demo. This is the code that I have

   # Form the MATLAB script command that processes images and write to
    # temporary results file.
    f, output_filename = tempfile.mkstemp(suffix='.mat')
    os.close(f)
    fnames_cell = '{' + ','.join("'{}'".format(x) for x in image_fnames) + '}'
    command = "{}({}, '{}')".format(cmd, fnames_cell, output_filename)
    print(command)

# Execute command in MATLAB.
    mc = "C:\Program Files\MATLAB\R2016a\bin -nojvm -r \"try; {}; catch; exit; end; exit\"".format(command)
    pid = subprocess.Popen(
        shlex.split(mc), stdout=open('nul', 'w',) cwd=script_dirname)
    retcode = pid.wait()
    if retcode != 0:
        raise Exception("Matlab script did not exit successfully!")

And this is the error I'm getting:

Traceback (most recent call last):
File "selective_search.py", line 63, in <module>
    boxes = get_windows(image_filenames)
  File "selective_search.py", line 36, in get_windows
    shlex.split(mc), stdout=open('nul', 'w')) #, cwd=script_dirname)

    startupinfo)
FileNotFoundError: [WinError 2] The system cannot find the file specified

I've already added my matlab path, which I found by appending \bin to the result of matlabroot, and swapped \dev\null to nul. Is there something else I'm missing here? I'm on windows, which I think is causing the problems (I had previously managed to get this code working on mac).
