"Difficulty opening ..." Error Using Fastsearch Index
Why am I getting this "Difficulty opening ..." error using Fastsearch Index files?
✍: FYIcenter.com
When you are using a fastsearch index file as the input, you must keep the original molecule data files
in the original location, because the index file has references to the original data files.
If those original data files are removed or moved to another location, "babel" will give this "Difficulty opening ..." error.
The following command session shows what happens, if you renamed the original data file after the index file was generated.
