2 Genetic data collection
Genetic data have been collected and analysed for several Ministry
of Fisheries projects on orange roughy (e.g., ORH9703, DEOR13,
MOF802A, FBOR01) and black and smooth oreo (e.g., DEE9801). Tissue
samples are collected either fresh in the field from trawl surveys,
or from whole specimens returned back to Greta Point.
The genetic materials are coded into ASCII files. The data are
managed in a file system and are collated and analysed in 3 PC
computer programs, with each program having their own ASCII input
file format. Figure 1 shows the file system set up for the management
of these genetic data. Each analysis program has its own directory,
or sub-tree, for storing it's own format of input file. Within
each of these directories, the data are further sub-divided by
project directories, with each project directory holding all the
input and output files generated for and by the relevant analysis
program. Any one project may have directories in none, one or all
three of the analysis program subtrees.
Data validation is currently carried out by Dr Peter Smith (NIWA),
who checks all data entries. In addition, the programs will not run,
or throw up spurious alleles, if data are entered incorrectly.
