Hi Netters,

I encounted problems when assumbling contigues using XDAP in STADEN.

Here is the output messages.  Could somebody tell me what's the problems?

 New gel reading overlaps contig     1
 New gel already in database with number     3 Entry aborted
 Failed gel name written to error file
Batch finished
  12 sequences processed
  3 sequences entered into database
  0 joins made
 >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

QUESTIONS:

1)  There is good homology between the contigs, why is only 3 of 12 
assumbled?

2)  There was a error message:

    " Overlap between contigs     1 and     1
      Trying to form loop in contig  1
      Gel not entered
      Failed gel name written to error file"

   What did cause the "Gel not entered"?  Is the gel file name (15 
	letters) to long? 

3) What does this error message mean, "New gel already in database with
	number 3.  Entry aborted."?  
	The two gels have different file nambes. 

4) How to make the assumbling program working in my case?


Your help will be greatly appreciated.
