Various (Pre 1986) My first programs were written in BASIC on TRS-80 computers at high school (1981), then in UCSD Pascal on an Apple II+ I purchased as an undergraduate student.

 

CROWDY (1986) Modelling density effects on plant growth for ecological studies being done at the University of Canterbury.

 

Unnamed (1987) A simple operating system for a 4-processor overlapping-RAM computer developed at Computing Technology Limited (Christchurch, NZ). Programmed in C on a PC, cross-compiled to 6805 code, “burned” into an EPROM, installed into the multi-processor hardware and debugged using an oscilloscope.

 

NWAlign (1990) Needleman-Wunsch alignments of sequences.

 

DOTTY (1990) Dot plots for sequence comparisons.

 

DAWG, DAWGAlign and others) (1990–) Suffix tree methods for high-speed sequence searching and locating conserved motifs in unaligned sequences.

 

MotifAnal (1991–) An interactive database-style system for analysing large multiple alignments of protein sequences. This program (>20,000 lines of source code) was written in Pascal on Vax computers over several years. It has many features, including:

 
  • Construction of databases, including annotation options;
  • Use of arbitrary motif weight, amino acid property and amino acid similarity tables;
  • Conversion of amino acids property tables to amino acid similarity tables and standard operations on tables such as scaling, normalisation, symmetrising and so on;
  • User-specified position referencing schemes. Allows users to refer to positions in an alignment independent of the actual alignment position. Provides a referencing scheme that withstands later revision of alignments such as later inclusion of longer loop sequences.
  • Related positions that are not sequentially adjacent in the alignment (eg. active site residues) can be referred to in convenient manner;
  • Calculation and plots of the conservation of each position in an alignment, output in plain text or Postscript. Conservation tables can be compared to determine co-conservation and the like;
  • Complex comparisons can be generated using a range of user-specified options, filtering “masks” and commands. Subsets of the alignment (certain sequences, certain positions within those sequences) can be passed to each of the analysis options, based on criteria such as named sequences and positions, the amino acids present at named positions, the score of the selected positions against a mask sequence, optional use of position weight tables and so on;
  • Statistics of properties can be output;
  • Correlations between alignment positions can be calculated and output;
  • The number of amino acids between positions can be used as a property;
  • Duplicate entries can be eliminated if desired;
  • Phylogenies of motifs can be constructed, including “group phylogenies”; an early pre-descendent of the evolutionary trace methods that are now widely available
 

WHEEL (1991) Depiction of protein sequence (family) conservation on “helical wheels” with PostScript™ output.

 

SITEPRED (1991–1992) Prediction of active site residues from large multiple sequence alignments of protein families with divergent functions. Successful application of this approach to CCHH zinc fingers resulted in a single author article in EMBO Journal (Jacobs, 1992). Predates methods subsequently published to predict functional residues from alignments.

  • Perl module to process Unix command line options and the like: GHJ_UnixShell (1999–);

Biography


In the final year of my B.Sc.(Hons) (1986, 1st Class) in which I studied both biology and computer science, I “discovered” bioinformatics which offered a niche where I could exploit my interests in both molecular biology and computer science.


After completing my degree I worked as a computer programmer (Computing Technology Ltd.). After hours I taught myself bioinformatics by reading the research the literature at the local university library. From this I drew up my own research proposal, eventually obtaining a Ph.D. studentship in the Structural Studies section of the MRC Laboratory of Molecular Biology at Cambridge University. There I studied under Dr. Andrew McLachlan (FRS), one of the founders of bioinformatics who published his first bioinformatics paper in 1969, along with Sir Aaron Klug (FRS, OM, Nobel laureate, Chemistry, 1982) and Dr. Daniela Rhodes and others.


My Ph.D. research focused on DNA-binding proteins, in particular the bZIP and CCHH zinc finger protein families. This research included molecular dynamic simulations of proteins, sequence analysis, studies of protein-DNA complex structures, basic phylogenetics and development of a large program to analyse protein motifs written over several years. This work includes correctly predicting the DNA-binding residues of zinc fingers from sequence analysis (Jacobs, GH, EMBO J. 1992).


Since leaving Cambridge, I have continued to study protein-DNA interactions, spent a period doing genetic linkage analysis and programming maintaining the Transterm database and presenting it as an interactive website.


More recently, I have established myself as an independent scientist, setting up BioinfoTools as a vehicle to deliver my bioinformatics software and consulting services. Having reviewed where bioinformatics and computer programming is headed, a portfolio of projects has been developed from a log of research ideas which has been maintained over many years. Using this, I am now bringing the most promising projects to life.


Supported by with Amonida Zadissa and Anar Khan I co-coordinate the local Bioinformatics Club whose members are drawn from several departments of the local university and local biotechnology companies. I am a member of the local biotechnology cluster (bioSouth) and frequently contribute to national taskforces in bioinformatics and biotechnology.
