re: Ace-MODS urgent help!!
Dave Matthews
Yes, this modification is well tested and quite stable. But you're right,
you need some documentation to use it. What's available is sketchy and
dispersed.
First, you don't have to make any changes in your models.wrm or your .ace
data. What you do is create a rule in wspec/markup.pl that is used by
AceBrowser to parse the data and create the href link if there is a match
to the rule.
This example,
http://www.graingenes.org/cgi-bin/ace/tree/graingenes?name=BE403741&class=Sequence
has several links to external databases. Let's look just at the DB_info
line.
The ACEDB data for this is:
Sequence : "BE403741"
DB_info External_DB "GenBank" "BE403741"
AceBrowser has added the href links "[DDBJ|EMBL|GenBank]" according to the
rule in wspec/markup.pl.
The model for class Sequence is:
?Sequence ...
DB_info External_DB Text Text
The rule in markup.pl is:
##########################################
# Connection to external DB for Sequence #
##########################################
{'root'=> {'cl'=>'Sequence'},
'branch' => [{ty=>tg,va=>'DB_info'},
{ty=>tg,va=>'External_DB'},
{ty=>tx,va=>'GenBank'},
{ty=>tx}],
'urls' => [{'name'=>'EMBL', 'URL'=>'http://srs.ebi.ac.uk/srs6bin/cgi-bin/wgetz?-e+[embl-acc:$keys[0]]'},'GenBankAC',{'name'=>'DDBJ', 'URL'=>'http://getentry.ddbj.nig.ac.jp/cgi-bin/get_entry.pl?$keys[0]'}],
},
#
Documentation on writing these rules is given in
http://www.acedb.org/Cornell/ace95/nalwww.html#appendix3. Briefly,
"cl" means class, "ty" means type, "tg" means tag, "va" means value, and
"tx" means text. The value of that final ty=>tx field will be substituted
in for the variable $keys[0].
In this rule, 'GenBankAC' is the name for an URL that is defined in another
file, externalURLs, which is located in the AceBrowser configuration
directory. The GenBankAC line in this file should currently say:
GenBankAC:GenBank:http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Search&db=Nucleotide&doptcmdl=GenBank&term=$keys[0]
Writing these rules is actually easier than it looks, and there are a
lot of examples in the distributed markup.pl file.

I would counsel some caution, e.g. setting it up on a test machine first.
Hugh himself has been able to install it on two other servers but I don't
know if anyone has done it using only the instructions provided.

Thanks again for your help.I think I will take my chances and test
everything on a seperate copy of the database.In case of issues I
would need further technical clarifications..
thank you
