|---|
| 14 | |
|---|
| 15 | DESCRIPTION The 'PD RESULT' window is displayed automatically after |
|---|
| 16 | finishing the probe target searching or manually by pressing the |
|---|
| 17 | 'RESULT' button of the 'PROBE DESIGN' window. |
|---|
| 18 | |
|---|
| 19 | The parameters defined by in the 'PROBE DESIGN' window are |
|---|
| 20 | listed in the first few lines of the 'PD RESULT' window. |
|---|
| 21 | |
|---|
| 22 | |
|---|
| 23 | Description of single display columns: |
|---|
| 24 | |
|---|
| 25 | Column contains |
|---|
| 26 | |
|---|
| 27 | Target the target sequence of the designed probe |
|---|
| 28 | le length of designed probe |
|---|
| 29 | apos absolute 5'-position of the target sites |
|---|
| 30 | (most often targeted position) |
|---|
| 31 | ecol ecoli-relative position |
|---|
| 32 | qual a probe quality indicator (see below) |
|---|
| 33 | grps groupsize (number of perfect hits in target-species) |
|---|
| 34 | G+C G+C content |
|---|
| 35 | temp predicted dissociation temperature (4GC+2AT) |
|---|
| 36 | Probe the designed probe sequence |
|---|
| 37 | |
|---|
| 38 | The numbers of the next columns (from left to right) indicates how many |
|---|
| 39 | non-target species would be detected by this probe if the temperature would |
|---|
| 40 | be gradually lowered ('_' means no hits). |
|---|
| 41 | |
|---|
| 42 | The columns do only represent virtual temperature shifts and cannot be |
|---|
| 43 | assigned to degree centigrade! |
|---|
| 44 | |
|---|
| 45 | To write the results to an ascii file press the 'SAVE' button to display |
|---|
| 46 | the 'SELECTION BOX' window. |
|---|
| 47 | |
|---|
| 48 | The 'Auto match' toggle has the same meaning as in LINK{probematch.hlp}. |
|---|
| 49 | |
|---|
| 50 | SECTION SORTING |
|---|
| 51 | |
|---|
| 52 | The probes are sorted by quality. The quality tries to reflect how good |
|---|
| 53 | each probe separates between target- and non-target group. |
|---|
| 54 | |
|---|
| 55 | Therefore it detects the column COL in the decrease-temparature-list, where |
|---|
| 56 | more than twice as much non-target species get hitten than allowed. |
|---|
| 57 | |
|---|
| 58 | 1000 |
|---|
| 59 | quality = groupsize * COL + ---------------------- |
|---|
| 60 | 1000 + (hits in COL) |
|---|
| 61 | |
|---|
| 62 | |
|---|
| 63 | Probes with equal qualities are sorted by absolute position and |
|---|
| 64 | then alphabetically. It does not take G+C content, temperature |
|---|
| 65 | or ECOLI position into account. |
|---|
| 66 | |
|---|
| 67 | It is up to the user to study the list carefully and choose his |
|---|
| 68 | candidates. In our lab we often found the 20th probe was the best. |
