sQanner is a simple web tool to evaluate the polyQ landscape of a proteome. It takes a proteome and generates a plot with the number of pure and impure polyQ, and the polyQ length distribution per threshold. A threshold is defined as the minimum number of glutamines required in a protein region of a given size to consider it a polyQ. The thresholds used in sQanner are 4/4, 4/6, 6/6, 6/8 and 8/10. The whole process takes ~10 seconds for the proteome of Saccharomyces cerevisiae (~6k proteins) and ~2 minutes for the proteome of Homo sapiens (~75k proteins).
