Hi!

I am having this issue when trying to run Cluster_Ensembles in a CentOs machine. I have already installed metis and apparently is running.

Do you know what can be giving the error?

INFO: Cluster_Ensembles: cluster_ensembles: due to a rather large number of cells in your data-set, using only 'HyperGraph Partitioning Algorithm' (HGPA) and 'Meta-CLustering Algorithm' (MCLA) as ensemble consensus functions.

Maybe, this issue is related to a deeper problem in the wrapped hmetis.

Hi,

Any update on this?

I'm having the same error:

`INFO: Cluster_Ensembles: cluster_ensembles: due to a rather large number of cells in your data-set, using only 'HyperGraph Partitioning Algorithm' (HGPA) and 'Meta-CLustering Algorithm' (MCLA) as ensemble consensus functions.
