This function is used to show the relationships of the gel readings in the database in three ways.
In the above illustration, a single contig, all contigs, a file or list of contigs can be selected. For a single contig, the contig identifier and range selector becomes enabled. Choosing a file or list enables the "browse" button which will invoke either the file or list browser respectively. When "all" contigs is selected a further choice is available: whether to `Show readings in positional order'. This question determines whether to output in method 1 (No) or 2 (Yes) listed above.
The function is particularly useful for creating files or lists of
reading names. To create a list of reading names run Show Relationships
to produce the desired output to the Output Window. Then either use cut
and paste from this window to a list editor, or use the right mouse
button in the output window to request the "Output to list" option. In
this latter case the header "
CONTIG LINES" and "
lines should be removed (although most functions will happily ignore,
with warnings, a list containing unknown reading names).
Below is an example showing a contig from position 1 to 689. The left gel reading is number 6 and has archive name HINW.010, the rightmost gel reading is number 2 and is has archive name HINW.004. On each gel descriptor line is shown: the name of the archive version, the gel number, the position of the left end of the gel reading relative to the left end of the contig, the length of the gel reading (if this is negative it means that the gel reading is in the opposite orientation to its archive), the number of the gel reading to the left and the number of the gel reading to the right.
