[daip] Fwd: Problems loading FITS data into AIPS

[Richard Townsend]

Hi,

So I installed AIPS for the very first time yesterday, and, although it took
me quit a while, I finally got it up and running without any error messages.
My main goal with this piece of software is to display images similar to the
graphs in chapter 6 of the cookbook. However, I have run into some issues in
trying to read a FITS file in AIPS. Following the various instructions as
well as I could, here is the background info of my problem:

I am running Ubuntu, if that makes a huge difference.

The file I am trying to read is called sequence29.fits and it is in the
directory /home/rtownsend/Dowloads/. In my terminal, I did:

$MYAREA=/home/rtownsend/Downloads; export MYAREA

Then, while running AIPS, I did the following:

TASK 'FITLD'
DATAIN 'MYAREA:SEQUENCE29.FITS'
GO

The got the following output in my MSGSRV window:

localh> FITLD1: Task FITLD (release of 31DEC10) begins
localh> FITLD1: Create FITLD             .TEMP     .    1 (MA)   on disk  1
cno   1
localh> FITLD1: TAPIO: RECORD LENGTH    128 INCONSISTENT WITH BLOCK SIZE
2880
localh> FITLD1: IMGDAT: COULD NOT READ INPUT.   IER=   10
localh> FITLD1: ERROR     1 RETURNED FROM IMGTAP
localh> FITLD1: Destroyed  1 extension files of type HI
localh> FITLD1: Destroyed MA image file: catno=    1 disk=1
localh> FITLD1: Purports to die of UNNATURAL causes
localh> FITLD1: localhos 31DEC10 TST: Cpu=     0.0  Real=     0
IO=             1

I assume that the fourth line of output means that the task failed, but,
unfortunately, I couldn't find any documentation to explain to me what TAPIO
or IMGDAT refers to. If you could offer any help at all that would be
fantastic. To reiterate, I am trying to read the data from the file
sequence29.fits, and then plot it on a graph. I will attach the file in case
that is the problem. Thank you!

Sincerely,
Richard Townsend
