Hi!
When copying a sequence over the +1 site of the sequence, the sequence is "splitted" by a new line. Although, that shouldn't be like that (because the real molecule is circular), the real issue comes copying the reverse complementary.
To make it easier, lets say that the circular sequence (2000 bp) "ends" with "Ts" and starts with "As":
Original sequence:
|+1
GGG
AGGAGGAGGAGGAG
TTTTTT
AAAAAA
TAATAATAATAATAATAATAA
2000|
Copying that region (Ctrl +c), UGENE returns:
GGG
AGGAGGAGGAGGAG
TTTTTT
AAAAAA
TAATAATAATAATAATAATAA
Removing the new line solves the problem:
GGG
AGGAGGAGGAGGAG
TTTTTT
AAAAAA
TAATAATAATAATAATAATAA
But copying the reverse complementary (Shif + Ctrl +c) returns:
AAAAAA
CTCCTCCTCCTCCT
CCC
ATTATTATTATTATTATTA
TTTTTT
Here removing the new line creates a sequence that doesn't exist:
AAAAAA
CTCCTCCTCCTCCT
CCC
ATTATTATTATTATTATTA
TTTTTT
The end result should be (reverse complementary to the original):
TTATTATTATTATTATTATTA
TTTTTT
AAAAAA
CTCCTCCTCCTCCT
CCC
Feature request: In the latest versions of UGENE it is possible to copy trough the +1 position like shown above. Nevertheless, that is only possible manually selecting the sequence with the circular view, but not with the Select range dialogue (Ctrl +a). It would be nice to have that option as well.
Thanks
