What do you mean by "spectral-line analysis"?

For spectral-line cubes, you can do Gaussian fitting with
XGAUS.  For Zeeman-splitting, you can follow XGAUS with
ZEMAN.   To make moment images there are XMOM and MOMNT.
GAL can fit rotation curves to these for HI galaxies.   WARP fits
warped galaxies.  CUBIT does advanced model fitting to galaxy
cubes.  IRING can integrate in ovals.  

The JVLA makes "spectral" cubes even of continuum-type sources.
Polarization rotation measures are analyzed with FARS (plus AFARS etc)
and the RMFIT.

There are Gaussian fitting tasks IMFIT. JMFIT, and SAD.

And much more - I need to know what you need.  And I only speak for
me/AIPS not for "NRAO" anyway.  If you asked management they
would point you at CASA - although I suspect that CASA is way more
deficient in analysis tasks than AIPS.
