             Records), data elements file.

d2004.bin  - Descriptor data elements file.

mtrees2004.bin  - MeSH main headings with the tree numbers that place the
                  heading in a hierarchical arrangement.  Sorted by tree number.

q2004.bin  - Qualifier data elements file.

stree2004.bin  - Not a MeSH vocabulary file.  This file was created by us
                 specifically for the Repository.  The file contains a mapping
                 of MeSH Heading to Semantic Type per the given year.  The 
                 file was created using a combination of the d2004.bin "ST ="
                 fields and relevent UMLS files (MRCON, MRSTY) appropriate
                 to the given year.
