A.4 Startup Customization

There are two initialization files that are loaded upon startup. The first is loaded very early in the startup of casapy:

~/.casa/prelude.py

This allows for limited customization of the casapy environment, e.g. setting the path to an alternate logger. The second startup file should be used for most purposes:

~/.casa/init.py

This file is loaded just before the casapy prompt is display. This is the place where users can load their own python modules and casa tasks. For example /.casa/init.py might contain:

import os
sys.path.insert(1,os.environ[’HOME’]+os.sep+"python")
import analysisUtils as aU

and analysisUtils.py might contain:

import numpy as np
from mpfit import mpfit
from pylab import *
from numpy.fft import fft
from scipy import polyfit
import taskinit as ti
from importasdm import importasdm

Many options can also be set in the file

~/.casarc

E.g.
