    <p>I have a file stored in a hash with a value being an array. I would like to compare the arrays with each other and if they match exactly then store them in an array. </p> <p>For example:</p> <blockquote> <p>@geno1 = NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,A,NN,NN,NN,NN,NN,NN,NN,A,NN,NN,NN,NN,NN,NN,T,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,A,G,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,G,NN,NN,NN,NN,G,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN</p> <p>@geno2 = NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,A,NN,NN,NN,NN,NN,NN,NN,A,NN,NN,NN,NN,NN,NN,T,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,A,G,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,G,NN,NN,NN,NN,G,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN</p> </blockquote> <p>In this this matches exactly, Then I would like to store them in an array. If they are different even by one element. Say,</p> <blockquote> <p>@geno2 = NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,A,NN,NN,NN,NN,NN,NN,NN,A,NN,NN,NN,NN,NN,NN,T,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,A,G,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,G,NN,NN,NN,NN,G,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,NN,A</p> </blockquote> <p>In this the last element is A. So that shouldn't be stored in the array. If there is a way to do this without lopping through the array would be great. Since I have to run this on 10k samples and more frequently. </p>

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.
