Rapid Miner slow (failing ?) to load data

Hi everyone,

I'm clustering Facebook data using K-means and the cosine similarity measure.

I have about 600 hundreds attributes for about 300 persons. My CSV file is 410ko.
It appears that Rapid Miner fail to load the data and I don't understand why.

Here is what hapenned : I launched the process, but after 1h running (I did my laundry in case you wonder  ;) ) I decided to stop it. I had a look at the log and here is what I found :
Mar 14, 2013 5:00:46 PM INFO: Process //NewLocalRepository/with-profile-info starts
Mar 14, 2013 5:00:46 PM INFO: Loading initial data.
Mar 14, 2013 6:03:51 PM INFO: Process stopped. Completing current operator.
I believe this means that the clustering didn't even start. Am I wrong ?

Do you have any idea, on what I should to about that ?

Thanks a lot.

    can you try the CSV Import wizard (File -> Import Data -> Import CSV File)? Does it work that way?

    Hello Marco,

    Thanks for your answer, this is actually what I'm already doing.

    [edit] I just gave it one more try, (on saturday morning... ;D) and it's working now. I believe the error may had nothing to do with Rapid Miner, it seems that a simple reboot may have solved it :s. So I apologize for the useless topic).
