yank |
Function
Reads a sequence range, appends the full USA to a list fileDescription
yank is a simple utility to add a specified sequence name to a list file.In fact, it writes out not just the name of the sequence, but also the start and end position of a region within that sequence and, if the sequence is nucleic, if can specify whether the sequence is the reverse complement.
Without the program yank you would need to use a text editor such as pico to create the appropriate list files. yank makes this process easy.
List Files
Many EMBOSS programs can read in a set of sequences. (Some examples are emma and union) There are many ways of specifying these sequences, including wildcarded sequence file names, wildcarded database entry names and list files. List files (files of file names) are the most flexible. yank is a utility to add sequences to a list file.Instead of containing the sequences themselves, a List file contains "references" to sequences - so, for example, you might include database entries, the names of files containing sequences, or even the names of other list files. For example, here's a valid list file, called seq.list:
unix % more seq.list opsd_abyko.fasta sw:opsd_xenla sw:opsd_c* @another_list
This looks a bit odd, but it's really very straightforward; the file contains:
- opsd_abyko.fasta - this is the name of a sequence file. The file is read in from the current directory.
- sw:opsd_xenla - this is a reference to a specific sequence in the SwissProt database
- sw:opsd_c* - this represents all the sequences in SwissProt whose identifiers start with ``opsd_c''
- another_list - this is the name of a second list file
Notice the @ in front of the last entry. This is the way you tell EMBOSS that this file is a list file, not a regular sequence file.
Usage
Here is a sample session with yankThis is an example of adding an entry for the part of tembl:hsfau1 between positions 1913 and 1915 to the existing list file 'cds.list':
% yank
Reads a sequence range, appends the full USA to a list file
Input sequence: tembl:hsfau1
Begin at position [start]: 1913
End at position [end]: 1915
Reverse strand [N]:
Output file [hsfau1.yank]: cds.list

Input file format
yank reads any valid sequence USA.You will be prompted for the start and end positions you wish to use.
If the sequence is nucleic, you will be prompted whether you wish to use the reverse complement of the sequence.
