Subject: [Mead] Problems creating CIDR clusters on MAC OS
Message-ID: <6BD05DEA-C477-46DE-B27E-33EDA708C2F0@site.uottawa.ca>

Hello,

I am a new user of MEAD and I am particularly interested in using  
CIDR add-on to create document clusters. I run MEAD (and CIDR) on Mac  
OS 10.4.8.

When I run CIDR I get a new cluster for every document and the  
similarity between candidate documents is always 0, even if I try two  
documents which are identical. It seems that at least one person from  
the mailing list had similar problems on Red Hat Linux and that the  
problem appears to be connected to the ?dbmopen? subroutine. The  
suggested action was to replace ?dbmopen? by ?tie? which I did, like so:

tie %nidf, "DB_File", "nidf"

It appears to work in the sense that it does not crash, but I still  
have the problem of having a new cluster for each candidate document.  
I am not proficient enough in Perl to figure out what I am doing  
wrong and I would appreciate any suggestions.

Thanks in advance to anyone who can help.

Anna
