#You can parse Genbank bank files with BioRuby the standard way, but there's a hidden problem. If the file ends with blank lines, i.e. after the genbank terminator (two forwards slashes, //) there are empty lines, BioRuby reads these as additional, empty records. However, you can route around this by trimming the blank lines before handing it to the parser. | |

Bio::FlatFile.auto("foo.genbank").each_entry { |gb| | |

which will print the id of every sequence in the file. However, if the file ends with blank lines, i.e. after the genbank terminator (two forwards slashes, which the wiki markup doesn't like) there are empty lines, BioRuby reads these as additional, empty records: |

This is the easiest and most concise way of calling an external process in Java. The inheritIO methods causes the command to output stdout and errout to the same place as your current process (which most of the times is the console), no need to create mechanisms for reading asynchronously from input streams to get at the information. | |
