Figure 3. Comparation of time and accuracy between manual and automatic counting.
(A) The averaged evaluation times of both manual and automatized analysis (“yeast counter”) of the same sample. Student’s t-test (two-tailed), p<0.0001. (B) The colony-forming units of the last spot in spotting test for both manual and automatic counting, and the comparation between experimental and theoretical value. The manual (left column) count is quite different from what is expected (right column), while automatic counting (middle column) is closer to the theoretical value. Continuous lines indicate statistically significant differences, asterisks indicate the according p-value (p<0.001; p<0.1; Student’s t-test (two-tailed).
