I've a colorspace library. Everybody knows that SOLiD has low-quality ends from reads. So, I would like to know if there are one tool to check this quality graphically. Just like a dotplot of my reads quality.
qual 29 32 29 9 4 6 -1
And the graphics will be:
| G | G | G | W | W | B |
G = Good W = Warning B = Bad
Any help will be greatly appreciated.
