Max QGRS Length
(default is 30)
You can limit the maximum length of the QGRS sequences. The shortest possible QGRS is 10 nucleotides.
Minimum G-Group size
(default is 2)
The minimum number of tetrads in a G-quadruplex. For instance, QGRS with G-group size of 4 might look like:
GGGG
GA
GGGG
T
GGGG
GCTA
GGGG

HELP
Loop size
(default is from 0 to 36)
The user may specify a range of possible lengths for the loops. The range will apply to all three loops of the QGRS. By default, it will search for any loops.
Loops that contain sequence
You can specify a nucleotide sequence that at least one of the loops must contain. You can also specify a regular expression. For instance,
a{4,}
will search for loops with 4 or more consecutive
A
's.
Analyze a FASTA / RAW Sequence
Look for QGRS in a FASTA or RAW sequence.
Append a sequence to your process:

HELP
- Appending a sequence adds another sequence to your batch file.
