1. Traces:

 All directories: 103971 (unique)
 B_SPA : 102405  (unique) => 1566 missing

Best assembly:

 /fs/szasmg/Bacteria/Salmonella/S_enterica_paratyphi_A/edit_dir/B_SPA.fasta.screen.ace.83 
 $ grep ^CO *ace.83 | grep -v COMM | wc -l
 571

Longest contig:

 $ cat B_SPA.fasta.screen.ace.83
 AS 571 89509                                # 571 contigs, 89509 reads
 ...
 CO Contig1368 4813926 88824 1869182 C       # Contig1368 is 4813926, contains 88824 reads
 !!! Other Salmonella's are also 4.8M

The *.b1,*g1 reads seem to be mated!

Mate pairs:

 p(.*).[bg]1
 oyg(.*).[bg]1
 P_AA(.*).[bg]1

Estimate lib insert sizes:

 $ toAmos -ace B_SPA.fasta.screen.ace.83
 $ grep -c ^rds B_SPA.afg         # check if links were created
 $ more toAmos.error              # check if there were any convertion errors
 $ bank-transact -b B_SPA.bnk -m B_SPA.afg -c
 $ bank2contig B_SPA.bnk > B_SPA.contig
 $ cat B_SPA.contig | grep ^# | grep -v ^## | sort 
 # look at distances between mated reads

Create mate pair file (Bambus format, tab delimited)

 $ cat B_SPA.mates
    library small   2000    4000    (p).*
    pair    (p.*)\.b1$      (p.*)\.g1$
    
    library medium  4500    5500    (oyg).*
    pair    (oyg.*).b1$     (oyg.*).g1$
    
    library large   35000   45000   (P_AA).*
    pair    (P_AA.*).b1$    (P_AA.*).g1$

Rerun convertion utilities:

 $ toAmos -m B_SPA.mates -ace B_SPA.fasta.screen.ace.83 -o B_SPA.afg 
 $ bank-transact -b B_SPA.bnk -m B_SPA.afg -c
