Yes! This is by far the best way to do things, particularly if you are
new to principal component analysis. When you understand exactly what
each line in the script is doing and why, it's more convenient to have
one monolithic script. When you don't, it's more beneficial by far to
do things in stages, as suggested by Marcelo. It not only aids in
understanding, but also make debugging far easier. Those new to PCA
may find this brief cpptraj tutorial helpful:
