Gcg file type

If this step fails, see step 1. Sometimes, although relatively rarely, steps 1 and 2 might not lead to expected results. There can be several reasons for such situation to occur:. GCG File Extension 2. How to open GCG file? Sequences in GCG format contain a dividing line between optional text heading and the sequence data.

Consider the following example of a typical dividing line:. The sequence type should appear on the dividing line as either Type: N for nucleotide or Type: P for protein. If the dividing line doesn't contain a Type: field, GCG programs infers the sequence type from the characters in the sequence.

This inference may not always be correct. If the Type: field of any sequence is incorrect or missing, you should correct it with the Reformat program. For more information on Reformat, see the Program Manual. A list file, formerly known as a file of sequence names, is what its name implies: a file containing a list of sequence names and their locations.

You can think of list files as a way to organize your sequences on a project-by-project basis. List files are similar to bookmark files used by web browsers. They contain a link to the desired sequence s , but do not contain the actual sequence itself. You will find list files useful for specifying sequences from multiple files in one file that you can use as input to a program. List files can contain any number of the following types of sequences:.

You can use list files with any program that accepts multiple sequences as input. A program prompt asking "What sequence s? Below is an example of a list file. In addition to sequence specifications, each sequence in a list file may optionally contain sequence attributes. These attributes include:.

Begin Position. End Position. Sequence Topology: Linear or Circular. Sequence Weight. Wgt: n. That is, you may not want all sequences accounted for equally to determine a result. Therefore, you can give some sequences greater weight than others. This attribute is of use only when you are using two or more sequences in the analysis.

SeqLab uses the Join attribute to concatenate list file sequences in the Editor. Note: In version 9. File Type. SeqLab uses the file type to improve performance when loading files. Do not edit or delete the file type. This line must appear on the first line of the file. In previous software versions, this line was optional. This command assumes Perl 5.

If your directory has lot of list files, all ending with. Original files are backed up with a. Sequence List. You must provide the database or directory specification.

You can add sequences in any order. Sequence Attributes. Sequence Comments. Use a text editor of your choice and modify the file as necessary. Tip - One way to specify a subset of sequences is to "comment out" those unwanted sequences within the list file. Gene2Promoter or GPD allow the extraction of sequences. These information items are separated by a pipe symbol " ". The keywords are the following:.

Overview of Help-Pages. A unique identifier for the sequence. The positions are relative to the promoter region. Download File Analyzer here. Update info Upload example file. Suggest a program.
