So, first thing you have to do is to uncompress them. The command in UNIX is as follows:

Note: A compressed file is approximately 1/3 the original size. So you might want to make sure that you have enough disk space first.

Dear Colleague:

A new release of the MB-System software is now available via anonymous ftp.

MB-System is a software package for Unix computing environments consisting of programs which manipulate, process, list, or display multibeam bathymetry and sidescan data. MB-System is being developed at the Lamont-Doherty Earth Observatory of Columbia University with support from the National Science Foundation, SeaBeam Instruments, and Antarctic Support Associates.

The new version, 4.1, replaces the previous release of version 3.4 in December, 1993. This release includes many improvements to the package. Among the most significant changes are:

To obtain the compressed tarfile of the directory structure containing the source code, do the following:
% ftp lamont.ldgo.columbia.edu
Name: anonymous
Password: your_email_address

To uncompress:
% uncompress *.Z

To extract the directory structure, move the MB-System tar file to a disk with at least 50 MBytes of free space and do the following:
% tar xvf MB-System.4.1.tar

Information and installation instructions are found in the file mbsystem/README.

There are some additional files available by anonymous ftp that may be of interest:

The first two contain source code and fully linked executables for Xview (Sun SPARC) versions of two interactive graphical tools, mbedit and mbvelocitytool. The third contains some sample data files and example shellscripts demonstrating the use of some of the MB-System programs.

In the next few months, we expect our development effort will focus on the following issues:

When corresponding, please email to both of us, as one of us is generally out of town or otherwise unavailable at any given time. We will do our best to be responsive to bug reports and suggestions for improvements.

Cheers,

Dave Caress and Dale Chayes
