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

[Bill Cotton]

Aiyuan,
    TDD00004; is the only critical file.  There are several others that 
live in $DA00 but if not found AIPS task complain loudly but continue 
anyway.  If you copy the other files from a working $DA00 directory as 
well, it will reduce the screaming.  I'm not sure what happens when 
there "*"s in the path for DA00 (or other directories), it should look 
more like "/msn2a/bcotton/DA00" or your equivalent.

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.
