Body
I have a file filled with lines like this (this is just a small bit of the file): 9 Hyphomicrobium facile Hyphomicrobiaceae 9 Hyphomicrobium facile Hyphomicrobiaceae 7 Mycobacterium kansasii Mycobacteriaceae 7 Mycobacterium gastri Mycobacteriaceae 10 Streptomyces olivaceiscleroticus Streptomycetaceae 10 Streptomyces niger Streptomycetaceae 1 Streptomyces geysiriensis Streptomycetaceae 1 Streptomyces minutiscleroticus Streptomycetaceae 0 Brucella neotomae Brucellaceae 0 Brucella melitensis Brucellaceae 2 Mycobacterium phocaicum Mycobacteriaceae The number refers to a cluster, and then it goes 'Genus' 'Species' 'Family'. What I want to do is write a program that will look through each line and report back to me: a list of the different genera in each cluster, and how many of each of those genera are in the cluster. So I'm interested in cluster number and the first 'word' in each line. My trouble is that I'm not sure how to get this information. I think I need to use a for-loop, starting at lines that begin with '0.'The output would be a file that looks something like: Cluster 0: Brucella(2) # Lists cluster, followed by genera in cluster with number, something like that. Cluster 1: Streptomyces(2) Cluster 2: Brucella(1) etc. Eventually I want to do the same kind of count with the Families in each cluster, and then Genera and Species together. Any thoughts on how to start would be greatly appreciated!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
