[daip] The error of "No such file or directory: '**/DA00/TDD000004; " using AIPS

[Bill Cotton]

Aiyuan,
    Eric cced your query to me.
    One way or another the environment variable $DA00 needs to be set in 
the environment in which AIPS tasks are run and it must point to a 
directory in which a TDD000004; file in the format AIPS expects 
resides.  Obit writes the parameters in this file and the AIPS tasks 
reads them from there.  As you've noted the pipeline script tolerates 
failures in the plotting routines. Eric explained the standard AIPS 
setup which will define $DA00.  There is an Obit specific method, a file 
named .obitrc.py in either your home or the current working directory 
defines a number of items including those needed to run AIPS tasks.  A 
third possibility for which you obviously have at least a partial 
version of is the AIPSSetup.py file the calibration pipeline uses to 
define data directories and the like.  This can (usually does) include 
DA00.  My guess is that your version of this file either doesn't include 
DA00 or sets it to a directory that either doesn't exist or the 
TDD000004; file does not exist.   Ask Andreas about the proper location.
