Figure 1: An overview of mutant identification using MALDI-TOF. (a) Each identified peak is matched to an expected peak. (b) Each peak is compared to the preceding and succeeding peak in the graph and two quotas are calculated and stored. (c) A sample-set-wide mean and standard deviation is calculated for each peak set and compared to the standard deviation of each individual sample peak (arrows). Outliers above a preset threshold are flagged as “suspicious” (red arrows). (d) Data is presented in a table as well as a colour-coded sequence (not shown).
