Ribbon multiple alignment and trace file edition
![1](drex_bullet_1.png) Edit button
Options for editing the sequences.
|
|
![2](drex_bullet_2.png) More button
|
|
![3](drex_bullet_3.png) Align sequences and optimize directions
- Align the selected sequence only.
- Align all sequences.
- Reverse the direction of the selected sequence.
|
|
![4](drex_bullet_4.png) Find conflicts
Go from the selected position to the previous or next conflict.
|
|
![5](drex_bullet_5.png) Find sequence
Search for a given part of the sequence.
|
|
![6](drex_bullet_6.png) Base caller
This value is used to calculate the threshold level, depending on the selected algorithm in the Options dialog.
|
|
![7](drex_bullet_7.png) Zoom in/out horizontally
Adapt the width of the peaks.
|
|
![8](drex_bullet_8.png) Zoom in/out vertically
Adapt the height of the peaks.
|
|
![9](drex_bullet_9.png) Higher/Smaller
Enlarge the height of the sequence section.
|
|
![10](drex_bullet_10.png) Collapse/Expand
Collapse or expand the sequence section (expand to see the waves).
|
|
![11](drex_bullet_11.png) Show or hide chromatogram
Show or hide chromatogram for each of the nucleotides.
|
|
![12](drex_bullet_12.png) Confidence level
Show or hide the level of confidence of the consensus base pare at any given point of the alignment.
A confidence value can be computed for each nucleotide. The trace wave is giving the intensity of the signal for each of the four nucleotides.
|
|
![13](drex_bullet_13.png) Majority rule display
When checked this option will display the most frequent letter at any given point of the alignment.
|
|
![14](drex_bullet_14.png) Ambiguity letters
Letters displayed in the consensus sequence are ambiguity letters instead of majority rule letters.
|
|
![15](drex_bullet_15.png) Colored background
Letters will be displayed in black with colored background.
|
|
![16](drex_bullet_16.png) Show colored letters
Letters will be displayed in colors with a white background.
|
|
![17](drex_bullet_17.png) Regular interval
When checked, this option makes the interval between base pairs regular or standardized. Otherwise the original trace file file is displayed.
|
|
![18](drex_bullet_18.png) Redraw tree
Select one of the nine provided algorithms to (re)draw a tree based on the sequences.
|
|
![19](drex_bullet_19.png) Toggle tree display
Removes the drawn tree in front of the multiple alignment.
