Consensus Sequence Using SeqLogo

Hi,

I have alignments from Muscle in Fasta format, and i would like to obtain a consensus sequence using SeqLogo.

I saw that there is a component in Pipeline Pilot (v8) under Biology->Sequence Analysis->Readers->Utilities->Internals.

I give it a Fasta Alignment Reader component as input and a XY Scatter Plot Viewer as output.

However, i don't know how to configure the Sequence Logo component. It seems to be derivated from the bar chart component.

I tried to put accessionNumber as X Property and data as Y Property, but that throws me an error:

One or more properties of the required parameters is not defined or does not contain any values. For input string: "MMATITTSLFQRMGMMMKMMKFVLLFLLLLVLLFVSYAVSAEAVLSQAAEA"
java.lang.RuntimeException: One or more properties of the required parameters is not defined or does not contain any values. For input string: "MMATITTSLFQRMGMMMKMMKFVLLFLLLLVLLFVSYAVSAEAVLSQAAEA"

I didn't find neither documentation nor protocol that is using this component.

Any help would be appreciated.

Thank you.
