Contig mapping software

[Adam Sartiel]

In our mapping efforts, we try to determine the correct order of 
markers using YAc clones, in the final purpose of getting a full contig. 
A typical marker record consists of '+' and '-' for the corresponding 
positive and negative clones. The desired output would be something like 
this:
++++++
 ++++++++
    ++++
       +++++

etc.

Can anybody suggest software which might aid us in computing the optimal 
arrangement and presenting it nicely (on Unix, DOS, Mac or MS-Windows)? 

Thank you,

Adam Sartiel
