  • Field Details

    • singleLocationPattern

      protected static final Pattern singleLocationPattern
      parse a location. if group(1) is null than the feature is on the positive strand, group(2) start position, group(3) end position.

    • genbankSplitPattern

      protected static final Pattern genbankSplitPattern
      Decodes a split pattern. Split patterns are a composition of multiple locationsString qualified by actions: join(location,location, ... location): The indicated elements should be joined (placed end-to-end) to form one contiguous sequence. order(location,location, ... location): The elements can be found in the specified order (5' to 3' direction), nothing is implied about their reasonableness bond(location,location...location): Found in protein files. These generally are used to describe disulfide bonds. complement(location,location...location): consider locations in their complement versus takes in input a comma split location string. The split must be done for outer level commas group(1) is the qualifier group(2) is the location string to getFeatures. In case of complex splits it will contain the nested expression Not really sure that they are not declared obsolete but they are still in several files.

    • locationSplitPattern

      protected static final String locationSplitPattern
      designed to recursively split a location string in tokens. Valid tokens are those divided by coma that are not inside a bracket. I. e. split on the comma only if that comma has zero, or an even number of quotes ahead of it.
