[daip] AIPS Data Importing

[John M. Cannon]

Hello,

I have recently changed institutions and would like to import data  
(in AIPS format) that I worked with in my previous position.  I will  
try to be as specific as I can with what changes have occurred and  
what data I have.

First off, I was running AIPS previously on a PowerPC Mac G5 desktop  
system.  I was using an array of user numbers to differentiate among  
multiple projects.  So, in my AIPS data area, I have a few thousand  
files with standard AIPS nomenclature (e.g., MAD01M001.1XL;,  
MAD00C001.1XG;, MAD001001.1XJ;, to name just a few files with  
different user numbers).  All of these files were saved onto a  
portable disk & transported to my new institution.

I now have a small cluster of Intel-based Mac systems, each with AIPS  
31DEC07 successfully operating on it.  I would like to import the  
data I was using previously into the relevant data areas.  So, I have  
tried to simply copy these files into the DATA area as defined during  
my AIPS installations.  I get error messages that look something like  
the following:

AIPS 1: Loading a brand new POPS vocabulary

Copying files from the previous DA00 directory to the new one does  
not solve the problem; in fact, if I do this, AIPS does not start at  
all.   I have also attempted to create any requisite missing files by  
starting AIPS with a given userid and performing a few generic  
operations on a test image.  Subsequent copying of the files into the  
DATA and DA00 directories still does not work.

I find only sparse documentation on this particular issue.  One  
potentially relevant thread is the following:  http:// 
listmgr.cv.nrao.edu/pipermail/daip/2000-June/000397.html

Am I understanding that discussion correctly, that it may not be  
possible to read PowerPC-formatted files using an Intel machine?  I  
hope this is not the case, because much work will have to be  
reproduced......

Can you please advise on how to proceed?

Thanks so much,
John
