well, when I followed the Readme to install Pfam_scan, I couldn't find active_site.dat.gz in Pfam's ftp. In every post I check , it illustrated the file should be in http://ftp.ebi.ac.uk/pub/databases/Pfam/current_release/; but it isn't there! and I found the file with the same name in http://ftp.ebi.ac.uk/pub/databases/Pfam/Tools/ActSitePred/. However, when I download the active_site.dat.gz from http://ftp.ebi.ac.uk/pub/databases/Pfam/Tools/ActSitePred/, I got error below:

Use of uninitialized value $fam_id in hash element at /public/home/sunyq/miniconda3/bin/Bio/Pfam/Scan/PfamScan.pm line 807, <AS> line 1.

and I think may this file was just for test? and here's the content of active_site.dat.gz I downloaded.

SPEB_STRPY      experimental    192     
SPEB_STRPY      experimental    340     
PRTT_PORGI      pfam_pred       184     Aligns with SPEB_STRPY 
PRTT_PORGI      pfam_pred       327     Aligns with SPEB_STRPY

I'm really confused and need help. Is it the exact 'active_site.dat.gz' that I need to? If so, how to solved the error? Thanks! if it isn't the true file, could some please send me one?
