GUS 3.0: Web Sites and Tools June 20, 2002 Jonathan Crabtree

Outline " Current web interfaces – examples: allgenes.org, PlasmoDB.org – Java Servlet, CGI-based – reusable Java and Perl code, install scripts " The future? – PHP and JSP – "GUSWWW" schema redesign

allgenes.org query: "Is my cDNA similar to any mouse genes that are predicted to encode transcription factors and have been localized to mouse chromosome 5?"

Select the allgenes.org boolean query page Click on the "AND" button

Choose the RH map and GO function queries Select mouse chromosome 5 and "transcription factor"

There are 22 mouse RNAs (assemblies) that meet these criteria: This query result set now appears on the query "history" page:

Now use the BLAST page to identify RNAs similar to my cDNA The results of the BLAST search appear in the query history

Intersect ("AND") the BLAST search with the previous query: And we have our answer (the third row on the query history page):

Predicted GO function(s) (some manually reviewed) predicted protein CAP4 assemblyEST expression profile UCSC BLAT Other transcripts from the same gene External links Mapping information Protein/motif hits Gene trap insertions, etc.

PlasmoDB: Combining Expression and Sequence Data "List all genes whose proteins are predicted to contain a signal peptide and for which there is evidence that they are expressed in Plasmodium falciparum's late schizont stage."

cbil.gus.servlet.SiteServlet " extends javax.servlet.http.HttpServlet – and is the only actual servlet in our Java code " reads a configuration file and instantiates the set of JavaBeans defined therein: – instances of PageGeneratorI - content generators – SqlQuery - parameterized SQL queries – "Param" and "Formatter" classes " implements logging, dispatches requests

Features of Current [Servlet] Implementation " Automatic generation of HTML FORMs – Automated input checking – Integrated help features – INPUT elements populated from the database " Query history facility " Boolean queries (AND, OR, SUBTRACT) " Declarative configuration file " Base system is relatively independent of GUS

Limitations of Current Implementation " Relatively steep learning curve " Monolithic solution – No support for modifying configuration at runtime – All objects instantiated when config. file read " Limited ability to customize presentation layer (i.e., HTML) without programming in Java " Technical problems with Servlets/Tomcat – Must restart all servlets as a group – Not currently using Serializable sessions

Dynamic Web Content " HTML fragments embedded in a program: – CGI programs (e.g. Perl - interpreted) – Java Servlets (compiled) " Program fragments embedded in HTML: – PHP (interpreted) – JSP (compiled; once, as needed) " Another axis: persistent vs. not (CGI/FastCGI)

Program Fragments in HTML " Advantages: – faster development cycle; can edit in place – easier to see/validate structure of HTML pages – HTML has no functions, Java and PHP do " Disadvantages: – must take care to manage complexity of application " Recommendations: – move towards adopting this approach – move all persistent state into the database

PHP: PHP Hypertext Processor " " Scripting language; can be embedded in HTML " (Netcraft survey):

JSP - Java Server Pages " Based on and can interact with Java Servlets " Essentially Java embedded in HTML " XML-based tags, scriptlets, and JavaBean calls " Standard tag libraries available " Pages typically compiled on demand " Multiple implementations? (vs. single for PHP)

Next steps " Agree on desired user interface functionality – saving queries for PlasmoDB – persistent preferences for genome browser " Design parts of the schema to support it " Migrate old code/write new code " Easier to migrate existing code with JSP
