ToolBus/PathPort Web-Services
The PathPort project at VBI has implemented a number of web-services that provide the core data access and analysis tools capabilities for the system. These tools are utilized to provide the information that is displayed via the visualization plugins within the context of ToolBus. Most of these web-services simply wrap existing programs (e.g., Primer3, MUMmer 3.0) and databases (e.g., VBI's own bacteria phylogenetic and annotated DNA databases). Many of these resources are open-source and have no usage restrictions while others have restrictions.
Web-services can have restricted access because of the licensing terms of the underlying algorithm/software. Some programs, such as the GENSCAN have been acquired by VBI under the terms of an academic license, and therefore cannot be made available outside of VBI.
IMPORTANT NOTE:
For those of you working from behind VERY restrictive firewalls,
please note that all VBI services are published on ports 6565 and 7575.Data Services

A database of protein interaction pathways involved in the infection process for pathogens from both the CDC's and NIAID's A, B, and C pathogen lists. Currently only pathways for a few pathogens are present, but VBI's researchers are continuing to gather and curate data for this fully referenced and growing database. If you have specific questions, concerns, or suggestions regarding this information please email us at pronet@vbi.vt.edu- http://pathport.vbi.vt.edu/services/wsdls/beta/piml.wsdl
A database of background information on pathogens from both the CDC's and NIAID's A, B, and C pathogen lists (CDC list, NIAID list). Includes taxonomic, epidemiological, laboratory work, and host information. This fully referenced data has been gathered and curated by VBI researchers. If you have specific questions, concerns, or suggestions regarding this information please email us at pathinfo@vbi.vt.eduThe piml web-service retrieves pathogen background information including sections on taxonomy, organism, epidemiology, host-list, and labwork. The information is fully referenced with links to PubMed abstracts when available. Currently, the pathogens are documented in Xindice database. Xindice is a database designed to store XML data (commonly referred to as a native XML database). The user selects a specific pathogen and the corresponding pathogen ID is submitted to Xindice database, whereupon, the returned pathogen document is displayed by the PIML viewer.- http://pathport.vbi.vt.edu/services/wsdls/beta/pimllink.wsdl
This webservice takes an organism name and tries to find a close match in the pathogen information database for it. It then retrieve pathogen information from PIML webservice. Currently it is used by the phylogenetic viewer so that users can click on tree tips to find corresponding background information on those tips if available in the database.
Algorithm: Pimllink webservice apply a similarity metric algorithm to get the most approximate pathogen name which is matching the user provided pathogen name, then fetch pathgen information with this most approximate matching string. PimlLink applied a new string similarity metric algorithm that rewards both common substrings and a common ordering of those substrings. In addition, the algorithm considers not only the single longest common substring, but other common substrings as well. The solution is to find out how many adjacent character pairs are contained in both strings by considering adjacent characters: not only the characters, but also the character ordering in the original string are taken into account, since each character pair contains some information about the original ordering.- http://pathport.vbi.vt.edu/services/wsdls/beta/phylogenetic.wsdl

http://206.225.85.121:8080/axis/services/phylip?wsdlThe Phylip web-service takes a group of sequences to generate a tree using Phylip package and PAML package. The Phylip package contains many programs for inferring phylogenies. It carries out different algorithms on different kinds of data. PROTPARS estimates phylogenies from protein sequences(input using the standard one-letter code for amino acids) using the parsimony method, in a variant which counts only those nucleotide changes that change the amino acid, on the assumption that silent changes are more easily accomplished. DNAPARS estimates phylogenies by the parsimony method using nucleic acid sequences. Allows use the full IUB ambiguity codes, and estimates ancestral nucleotide states. Gaps treated as a fifth nucleotide state. DNAML estimates phylogenies from nucleotide sequences by maximum likelihood. The model employed allows for unequal expected frequencies of the four nucleotides, for unequal rates of transitions and transversions, and for different (prespecified) rates of changes in different categories of sites, with the program inferring which sites have which rates. PAML package contains programs for phylogenetic analyses of DNA or protein sequences using maximum likelihood (ML). The program CODEML is formed by merging two old programs: codonml, which implements the codon substitution method of Goldman and Yang(1994) for protein-coding DNA sequences, and aaml, which implements models for amino acid sequences. These two are now distinguished by a variable named seqtype in the control file codeml.ctl, that is, 1 for codon sequences and 2 for amino acid sequences.- http://pathport.vbi.vt.edu/services/wsdls/beta/blastbt.wsdl

http://64.92.170.71:6565/axis/services/mummergt?wsdlWraps the MUMmer 3.0 program developed by The Institute for Genomic Research (TIGR) for doing large sequence comparisons. It rapidly aligns entire genomes, as well as finds "Maximum Unique Matches" (MUMs) between two DNA or protein sequences. The central algorithm of MUMmer takes two input sequences and finds all subsequences longer than a specified minimum length that are identical between the two input sequences and their reverse complement. These matches are guaranteed to be maximal, in that they cannot be extended on either end without incurring a mismatch. The algorithm is implemented using a suffix-tree based data structure, which permits very fast and memory-efficient comparisons of the sequences. Currently, VBI hosts the following mummer flavored webservices, each running the same algorithm but contacting different databases.- http://pathport.vbi.vt.edu/services/wsdls/beta/mummer.wsdl The MySQL database contains sequence and annotation information from NCBI's RefSeq and/or Genbank database.

- http://pathport.vbi.vt.edu/services/wsdls/sean.wsdl
Sean webservice scans the aligned sequences a character at a time to find potential SNPs by comparing the individual character with the corresponding character in the consensus. If there is a difference in the sequence either side is checked against the same region in the consensus over the required window. By default this is set to 15 bp and is configurable by the user. If the windows are identical the position of the base change and the base are noted, only if at least one other identical base change is located at the same location in another sequence is it stored as a potential SNP. The only other check is to ensure that the consensus character is present in at least two sequences also as the consensus does not always contain the dominant base at a particular position. The results are returned in DAS/1 format.- http://pathport.vbi.vt.edu/services/wsdls/beta/glimmer.wsdl

http://206.225.85.121:8080/axis/services/glimmer?wsdlWraps the Glimmer 2.10 program, from The Institute for Genomic Research (TIGR), for doing gene prediction in genomic DNA sequences, especially the genomes of bacteria and archaea. It uses interpolated Markov models (IMMs) to identify the coding regions and distinguish them from noncoding DNA. Glimmer consists of two main programs. The first is the training program, "build-imm", which takes an input set of sequences and builds and outputs the IMM for them. These sequences can be complete genes or just partial open reading frames (ORFs). The second program is Glimmer, which uses IMM to identify putative genes in entire genome. Glimmer automatically resolves conflicts between most overlapping genes by choosing one of them. It also identifies genes that are suspected to truly overlap, and flags these for closer inspection by the user. These ``suspect'' gene candidates have been a very small percentage of the total for all the genomes analyzed thus far. Results are returned in DAS/1 format.- http://pathport.vbi.vt.edu/services/wsdls/glimmerm.wsdl

"It is based on a dynamic programming algorithm that considers all combinations of possible exons for inclusion in a gene model and chooses the best of these combinations. The decision about what gene model is best is a combination of the strength of the splice sites and the score of the exons generated by an interpolated Markov model (IMM). The system has been trained for Arabidopsis thaliana and Aspergillus and should work well on closely related organisms." Results are returned in DAS/1 format.- http://pathport.vbi.vt.edu/services/wsdls/glimmerhmm.wsdl

Tico web service wraps up TiCo package, "a tool for postprocessing predictions of prokaryotic genes with the objective to improve the accuracy of annotated Translation Initiation Sites (TIS)." "Currently the tool can be used to analyze and reannotate predictions obtained by the program GLIMMER2 (Delcher et al., 1999). The underlying algorithm of TiCo is based on a completely unsupervised method for scoring potential translation starts. The method works without specific assumptions about characteristic sequence features such as Shine-Dalgarno motifs or start codon usage. In addition, empirical thresholds have been avoided in order to prevent the algorithm from specialization with respect to particular test data."

http://206.225.85.121:8080/axis/services/kmean?wsdlUtilizes an R package based program, Kmeans, to perform non-hierarchical cluster data analysis. Algorithm outline: This nonhierarchical method initially takes the number of components of the population equal to the final required number of clusters. In this step itself the final required number of clusters is chosen such that the points are mutually farthest apart. Next, it examines each component in the population and assigns it to one of the clusters depending on the minimum distance. The centroid's position is recalculated every time a component is added to the cluster and this continues until all the components are grouped into the final required number of clusters.- http://pathport.vbi.vt.edu/services/wsdls/rpca.wsdl

Wraps the GENSCAN program for doing gene prediction. It analyzes genomic DNA sequences from a variety of organisms including humans and other vertebrates, invertebrates, and plants. For each sequence, the GENSCAN web-service determines the most likely gene structure under a probabilistic model of the gene structural and compositional properties of the genomic DNA for the given orgamism. GENSCAN predicts genes based on a pre-built probabilistic model. The probabilistic model accounts for many of the essential gene structural properties of genomic sequences, e.g., typical gene density, the typical number of exons per gene, the distribution of exon sizes for different types of exons. GENSCAN also builds the model based on many of the important compositional properties of genes, e.g., the reading frame-specific hexamer composition of coding regions vs the (reading frame-independent) hexamer composition of introns and intergenic regions, and the position-specific signals, and of the TATA box, cap site, and polyadenylation signals. Importantly, novel models of the donor and acceptor splice sites are used which capture potentially important dependencies between positions in these signals. For human and vertebrate sequences, separate sets of model parameters are used which account for the manysubstantial differences in gene density and structure observed in distinct C+G% compositional regions of the human genome and the genomes of other vertebrates. Results are returned in DAS/1 format.- http://pathport.vbi.vt.edu/services/wsdls/genemark.wsdl
