Probe delete plot

To delete the active plot, select Plot and then Delete Plot from the Probe menus ... 

We notice that the plot background is black. This is the effect of not selecting the background to be transparent. Delete the picture and then switch back to Probe. Select Window and then Copy to Clipboard, and select the options as shown ... 

The next thing we would like to do is plot the hysteresis curve for this Schmitt Trigger. The hysteresis curve is a plot of V0 versus V N. We must delete the trace Vfl/IN/. Click the LEFT mouse button on the text V(VlNf. It should turn red, indicating that it has been selected. To delete the trace, press the DELETE key. You should have the Probe screen shown... 

The above methods do not take deletions and insertions into account. Argos (20) has described a way to utilize self-search matrices at a given probe length and based on Dayhoff mutations and residue properties. A visual cue for sequence repeats are stacks of high peaks contained in vertical column spans (e.g., 57,58). In this case, a plot of sequence position and the sum of search matrix scores at that position along a vertical column yield a curve of repetitive high peaks at the start site for each motif. In some cases, the method has delineated repeats where in 10 of them, each with about 35 amino acids, only one site is fully conserved (58).
