PIR-ALN is a curated database of protein sequence alignments derived from 
sequences and annotation in the PIR-International Protein Sequence Database.
Alignments fall into the following three categories: family alignments 
including sequences that are less than 55% different from each other; 
superfamily alignments containing sequences from different families; homology 
domain alignments containing homologous segments from different proteins. 
Annotation information like superfamily names, keywords and taxonomy are 
derived from the PIR-International Protein Sequence Database.

The file PIRALN.REF_Z contains the PIR-ALN database in compressed form. The 
PIRALN.NAM file is a text file containing the database citation. The other 
PIRALN.**X_Z files are compressed index files used by the PSQ and ATLAS 
database query software and are described further in the PRNBRF.TXT document
in the anonymous/pir/db_vms directory. 

!!!!!!!!!!!!!!NOTE CHANGES IN FILES AVAILABLE !!!!!!!!!!!!!!!!!

IT IS PIR'S INTENTION TO STOP PROVIDING INDEX FILES FOR THE
NBRF-PIR FORMAT AND THE CODATA FORMAT AFTER RELEASE 66.00!!

THE *.REF, *.SEQ, *.NAM, AND *.DAT FLAT FILES WILL CONTINUE.

IF YOU WISH US TO CONTINUE TO PROVIDE ANY OF THE INDEX FILES
PLEASE LET US KNOW. CONTACT PIRMAIL@NBRF.GEORGETOWN.EDU .
