Query related to conversion of segy file and .su files using Seismic Unix
hi

M using ubuntu 11.04....and has installed Seismic Unix on it....
I want to process some unprocessed segy data using Seismic Unix....
i have converted .segy file to .su using

segyread tape=file1.seg verbose=1 endian=0 | segyclean > smallfile.su

and got 3 files
-smallfile.su
-header
-binary
Now my queries are:
1. How to verify that .su file created is valid or not?
2. The .su file i got ....Is this the processed file?
-Or the processing is yet to be performed on this .su file?
-If it is processed how to read data from it?
2. How to convert .su file to .seg file?

as when m running

segywrite < smallfile.su tape=file1.seg verbose=1 endian=0 | < processedfile.seg
its giving error as
segywrite: fgettr.c: bad first header
plzz help..
Regards..

seeded-in-ubuntu(1)					      General Commands Manual					       seeded-in-ubuntu(1)

NAME

       seeded-in-ubuntu - Determine whether a package is safe to upload during a freeze

SYNOPSIS

       seeded-in-ubuntu [options] package...

DESCRIPTION

       Lists all the current daily images containing the specified packages.  Or whether the package is part of the supported seed.

       If it isn't on an image, it should be safe to upload.  During the final freeze, one should avoid packages in the supported seed too.

       An index of the current manifests is downloaded from UbuntuWire.

OPTIONS

       -b, --binary
	      The  packages  specified	are  binary packages.  This is faster than source packages, as otherwise we must query LP to determine the
	      binary packages that every specified source package builds.

       -u URL, --data-url=URL
	      URL for index of seeded packages.  Default: UbuntuWire's service at http://qa.ubuntuwire.org/ubuntu-seeded-packages/seeded.json.gz.

       -h, --help
	      Display a help message and exit

EXAMPLES

       All the images that contain unity:

	      seeded-in-ubuntu -b unity
