Making arrays in different ways....

In order to extract data for multiple proteins, there is a requirement to work with data from multiple proteins.
The question is how to arrange this data.
This is not an trivial question.

When I was extracting the Feature data for one protein, I extracted:

• type[i]
• desc[i]
• stat[i]
• start[i]
• end[i]

in separate arrays and then I used the "array" function to stitch these all together. This worked well because it held each feature in a separate array and then held the feature list together as well. 

I could delete a row when I wanted to remove a whole feature.

However, when I tried to do this for multiple proteins, I used the "push" function. Added the information as individual pieces. Now, when I try to delete, it doesn't remove a row but rather just the individual items. 

So "push" and "array" are very different.
