[StarCluster] Configuration error?

[Jackson, Xavier Jamel]

Hello, I am new to using Starcluster, and I am having issues setting up the configuration properly.  I followed all of the instructions in the Quick Start and the user menu.  Then I received this error when I tried to run:

$ starcluster start mycluster
StarCluster - (http://star.mit.edu/cluster) (v. 0.95)

Which didn't make sense to me, since I can run instances directly from aws with the credentials I used.  I read that you can use Ipython to check  that the credentials are valid, so I attempted to set up the Ipython plugin, then I got this error:

$ starcluster start mycluster

!!! ERROR - invalid node_instance_type specified: 't1.micro
[plugin ipcluster]
SETUP_CLASS=starcluster.plugins.ipcluster.IPCluster'
must be one of: m3.large, m1.small, c1.medium, cg1.4xlarge, t1.micro, cr1.8xlarge, c3.large, c3.xlarge, m1.large, hs1.8xlarge, c3.2xlarge, c3.4xlarge, hi1.4xlarge, i2.8xlarge, m2.2xlarge, m3.2xlarge, c1.xlarge, g2.2xlarge, m2.xlarge, c3.8xlarge, cc1.4xlarge, m1.medium, i2.xlarge, m3.medium, cc2.8xlarge, i2.2xlarge, i2.4xlarge, m1.xlarge, m2.4xlarge, m3.xlarge

I don't know why the configuration is treating the plugin as an extension of the node instance, especially since I didn't use any ' ' when entering the information.

Can anyone help with either error?  I will try playing around with it to find a fix, but I am a bit confused as to how to get the configuration to work.
