CLASS 2
All elements match but not all in the correct order



CLASS 3
Not all elements match but those that do are in order



CLASS 4
Remaining partial matches

   The program reports hits in four classes.

   Class1:
          Matches where all elements of a motif exist in the correct
          order

   Class2:
          Matches where all elements exist but some are in the incorrect
          order

   Class3:
          Matches where some elements match and are in the correct order

   Class4:
          Miscellaneous matches

Data files

   The data file is stored in the PRINTS directory of the standard EMBOSS
   data directory.
     * prints.mat Matrices derived from PRINTS
     * Pxxxxx Information for each fingerprint

   The column information is described at the top of the matrix data file

Notes

   The matrix information used to scan a sequence is derived from the
   final motif sets in the PRINTS database. The matrices are of the
   simple frequency type and contain the number of times a residue occurs
   in each position of the alignment. Each matrix therefore has a highest
   possible score, being the sum of the maximum score of each column. A
   match to the sequence window is obtained if it has a score equal to or
   greater than the percentage of the maximum score of the lowest scoring
   sequence in the final motif set.

   The data files must have been created before running this program.
   This is done by running the printsextract program with the
   "prints.dat" file from a PRINTS release. You may have to ask your
   system manager to do this.

Warnings

   The program will warn you if a DNA sequence is given.

Diagnostic Error Messages

   If you get the following EMBOSS FATAL ERROR message:

"prints.mat file not found. Create it with printsextract."

   then your local PRINTS data has not been set up correctly in your
   EMBOSS DATA directory. Use 'printsextract' to do this.

Exit status

   It exits with status 0 unless an error is reported.
