Precision execution failed

[akileshbadrinaaraayanan]

When I run: accept approx 4 <directory_of_c_code>

Precise execution failed.
Could not open timing file ({0}). This is probably because the ROI markers were not called.

Can some one explain what this error is and possibly give a fix to it?

Hi! This is indicating that your accept_roi_begin() and accept_roi_end() markers, described here, are missing.
