Alignment of query and comparison sequence for HELP SAMPLE

The above example shows the detailed relationship between the two sequences. From this graph you can see that there are at least 3 major blocks conserved in the query sequence. Using the other graphs and plots on this page will help you pinpoint the location of these conserved blocks. The data used to generate this plot is in "Probability Profile" File which can be viewed by clicking on the URL near the bottom of this page.
Probability of residue conservation in query sequence for HELP SAMPLE

The above example graphs the probability of conservation of each residue in the query sequence. This is equivalent to collapsing the "Alignment of query and comparison sequence" graph along the data(comparison) axis. You can see that the conserved sequences are approximately (1-68), (71-115) and (255-265). The data for this graph is in the "Marginal probability of the query sequence" file which can be viewed by clicking on the URL near the bottom of this page.

The above example show the probability of conservation of each residue in the query sequence. This is equivalent to collapsing "Alignment of query and comparison sequence" graph along the data(comparison) axis. This plot is also equivalent to the "Probability of residue conservation in query sequence" graph but shown as a temperature plot instead. The color indicates the degree of conservation. Red means that the base is highly conserved and the color blue means it is poorly conserved. From this plot you can clearly see that the conserved blocks are (1-67), (72-105) and (256-263). The data for this graph is in the "Marginal probability of the query sequence file" which can be viewed by clicking on the URL near the bottom of this page.

Data files

The URLs above are the data files used to make the graphs and other important information.

The "Run file output" includes the various probabilities for the number of conserved blocks. This example shows that probability that there are exactly 3 conserved blocks is 0.281207 and exactly 4 conserved blocks is 0.273431.
The probability that there are more than 3 conserved blocks is 0.633378
and more than 4 conserved blocks is 0.359946. (click on the "Run file output" URL to see the actual data)
The "Block alignment file" includes the most probable block alignments. In this example it shows that the most probable conserved blocks are
(1-67) (72-105) and (256-263). (click on the "Block alignment file" URL to see the actual data)

(see Bioinformatics 1998;14(1):25-39 for detail explanation of bayesian aligner)
