[Bioperl-l] Problem with clustering analysis of a large dataset ( 18000 rows and 17 columns)

Hi.
Thanks for your reply.
I have done the same job under the MS Windows 2000 (using Eisen's original 
cluster software for Windows) with the same computer (Pentium 4 2.4G with 
512M memory) and the same method (avarage linkage clustering algorithm), 
and the job was done in about 30 minutes, while the job failed under RedHat 
9.0. Is the difference caused by the different OS or some other reasons? 
I have another question about MCL. Could this method be used for gene 
expression dataset not only for clustering proteins ?

Sincerely
