GENtle/Sequence map

__NOTOC__ thumb|The sequence map. The sequence map is used by most GENtle modules. It shows sequences of DNA or amino acids, as well as primers, features, restriction sites and more. The basic behaviour, however, is always similar. Clicks A double click usuaqlly opens the editor for the sequence. Context menu The available functions in the context menu vary with the module the sequence map is used in, its state, and selection. Edit sequenceTurn on edit modeTransform sequenceInvert and/or complement the sequence (../DNA/ module only)Limit enzymesLimit enzymes so that only enzymes below a certain number of cuts in the sequence is shown (../DNA/ module only)PCRCompare DNA mapSelectionCompare DNA mapCopy as imageCopies the sequence map as a bitmap to the clipboard (Caveat : Such a bitmap can take up a huge amount of memory, depending on the length of the sequence)Save as imageSaves the sequence map in one of several image formatsPrint sequencePrints the sequence Keys The whole sequence can be marked by Ctrl-A. The ../Find/ dialog can be invoked by Ctrl-F. Both functions can also be called upon through a menu. In the DNA and PCR modules, the amino acid reading frame can be toggled by keys like this: Ctrl-1 = reading frame 1 Ctrl-2 = reading frame 2 Ctrl-3 = reading frame 3 Ctrl-4 = reading frame 1, complementary strand Ctrl-5 = reading frame 2, complementary strand Ctrl-6 = reading frame 3, complementary strand Ctrl-7 = all reading frames, one-letter code Ctrl-8 = known reading frames only (from the features) Ctrl-0 = hide amino acids Ctrl-W = three-letter code (not when displaying all reading frames) Ctrl-Q = one-letter code Edit mode Display and edit mode can be toggled by F2 or the toolbar. During editing, the sequence display is maximized, and the DNA map is hidden, improving ease of edit. Depending on the current module, only some keys are allowed (in the DNA module, "A", "C", "G", and "T") by default; any other key will trigger a request to allow all keys for that sequence, for that session. The cursor can be moved similar to that in a text editor. Insert and overwrite mode can be toggled, except for some modules like PCR or Sequencing, where overwrite mode is mandatory. In these modules, backspace and delete are diasbeled as well. When editing a primer in PCR mode, the "." key copies the base at the current position from the 3'→5' or 5'→3' sequence, respectively. Horizontal mode In some modules, the sequence display can be toggled to horizontal. This can enhance visibility. Printing, however, is always done in standard ("vertical") mode.
