tool: D191:         **** Mofext v1.0.3 ****


tool: D345: Usage: mofext -d mypatterns1.list mypatterns2.list -q GGATCC TTGANTGA -m matrix -w 10 -c 0.95



tool: D245: Options:


tool: D79: ~~~~~~~~


tool: D146: -h     Display full help.


tool: D136: -d     Databases to search. Space separated, maximum 50.


tool: D202: -q     Query patterns. Space separated, maximum 50.


tool: D349: -m     The similarity matrix.


tool: D295: -w     Wordsize. Default: 6.


tool: D427: -c     The similarity percentage limit (cutoff). Default: 0.8.


tool: D374: -o     Output format. See below.


tool: D145: Example:


tool: D344: mofext -d mypatterns1.list mypatterns2.list -q GGATCC TTGANTGA -m matrix -w 4 -c 0.5



tool: D138: Matrix:


tool: D320: ~~~~~~~


tool: D257:  The matrix used by mofext is a plain text file. Each row ends with a newline character.


tool: D363:  Columns are separated by one or more spaces. The matrix is quadratic, so A[j,i] = A[i,j].


tool: D117:  The number in the upper left corner denotes the matrix size. See default matrix included


tool: D416:  in the source.


tool: D126: Motif list:


tool: D178: ~~~~~~~~~~~


tool: D263:  The motif list file used by mofext is a plain text file. Each row ends with a newline character.


tool: D402:  The motif list file must have at least 2 columns, separated by spaces or tabs. The first column


tool: D189:  is a UNIQUE motif id. It can contain any characters except space, newline or tab. The second


tool: D159:  column is the sequence (pattern) of the motif. The available characters are the ones defined in


tool: D99:  the matrix file. Additional columns are ignored by the program.


tool: D335: Output:


tool: D39:  The -o option sets the output format of the program. The following characters represent an output


tool: D386:  element. The default is ieqd.


tool: D322:  i: ID column.


tool: D128:  s: Score.


tool: D228:  e: Extended score.


tool: D348:  p: Probability value.


tool: D34:  d: Hit subsequence.


tool: D154:  D: Full hit sequence.


tool: D22:  q: Query subsequence.


tool: D84:  Q: Full query sequence.


tool: D356:  F: The position of the first base of the hit subsequence in the full hit sequence.


tool: D372:  f: The position of the first base of the query subsequence in the full query sequence.


tool: D61:  %%: The similarity percent score of the hit/query subsequence pair.


tool: D182:  Example: mofext -d mypatterns1.list -q GGATCC -m matrix -o ied


tool: D59:  The program prints out the ID, extended score and the hit subsequence.
