| 13 | TITLE Probe Design parameters |
|---|
| 14 | |
|---|
| 15 | OCCURRENCE ARB_NT/Probes/Design Probes |
|---|
| 16 | |
|---|
| 17 | DESCRIPTION Allows to select the 'PT_SERVER' and its database, to customize |
|---|
| 18 | the presentation of the results, define the stringency of target |
|---|
| 19 | search and physical characteristics of the probes. |
|---|
| 20 | |
|---|
| 21 | Select the 'PT_SERVER' to use: |
|---|
| 22 | |
|---|
| 23 | Probe design is not run on your current database, but on |
|---|
| 24 | the database state at the time the PT_SERVER has been |
|---|
| 25 | updated (see LINK{pt_server.hlp}). |
|---|
| 26 | |
|---|
| 27 | After changing sequence data or species IDs or after |
|---|
| 28 | adding new sequences to the database, you need to |
|---|
| 29 | update the PT_SERVER to get correct results |
|---|
| 30 | (see LINK{probeadmin.hlp}). |
|---|
| 31 | |
|---|
| 32 | Length of output: |
|---|
| 33 | |
|---|
| 34 | Defines the number of probe target proposals to be |
|---|
| 35 | displayed in the 'PD RESULT' window (see LINK{probedesignresult.hlp}). |
|---|
| 36 | If more probes are found, the result list will be clipped. |
|---|
| 37 | |
|---|
| 38 | Max. non-group hits: |
|---|
| 39 | |
|---|
| 40 | Defines the maximum number of matched species accepted outside of the |
|---|
| 41 | group of species that have been marked. |
|---|
| 42 | If more species are matched by a probe, the probe gets discarded. |
|---|
| 43 | |
|---|
| 44 | This helps not to miss potential target sites in case |
|---|
| 45 | that species belonging to the particular specificity |
|---|
| 46 | group had been overlooked while marking. |
|---|
| 47 | |
|---|
| 48 | Max. hairpin bonds: |
|---|
| 49 | |
|---|
| 50 | Defines the maximum number of accepted, potential inter- and intraprobe |
|---|
| 51 | base pairings. |
|---|
| 52 | |
|---|
| 53 | !!! Not implemented !!! |
|---|
| 54 | |
|---|
| 55 | Min group hits: |
|---|
| 56 | |
|---|
| 57 | Defines the minimum fraction (%) of target species (=marked species) |
|---|
| 58 | which have to share the target site. |
|---|
| 59 | Probe targets matching fewer target species will be discarded. |
|---|
| 60 | |
|---|
| 61 | This helps to design multiple probes in case that common |
|---|
| 62 | target sites are not present in all species of the |
|---|
| 63 | particular specificity group. |
|---|
| 64 | |
|---|
| 65 | Length of probe: |
|---|
| 66 | |
|---|
| 67 | Defines the minimum and maximum length of designed probe targets. |
|---|
| 68 | Shorter or longer probe targets will be discarded. |
|---|
| 69 | |
|---|
| 70 | Temperature: |
|---|
| 71 | |
|---|
| 72 | Defines a range of allowed dissociation temperatures (= 4xGC + |
|---|
| 73 | 2xAU; centigrade) for designed probe targets. |
|---|
| 74 | |
|---|
| 75 | G+C content: |
|---|
| 76 | |
|---|
| 77 | Defines a range of allowed G+C fractions (%) for designed probe targets. |
|---|
| 78 | |
|---|
| 79 | ECOLI position: |
|---|
| 80 | |
|---|
| 81 | Defines a preferred sequence (alignment) region |
|---|
| 82 | for the probe target sites. |
|---|
| 83 | |
|---|
| 84 | The positions of that region have to be specified |
|---|
| 85 | relative to the E.coli molecule (Hint: ARB_EDIT4 displays the |
|---|
| 86 | E.coli position of the cursor in its top area). |
|---|
| 87 | |
|---|
| 88 | Doing so requires that: |
|---|
| 89 | |
|---|
| 90 | 1. your data was aligned (when PT_SERVER was updated) |
|---|
| 91 | |
|---|
| 92 | 2. there is a SAI named 'ECOLI' which |
|---|
| 93 | contains the reference sequence. |
|---|
| 94 | |
|---|
| 95 | Press the 'EXPERT' button to use individually weighted |
|---|
| 96 | base pairings (see LINK{pd_spec_param.hlp}). |
|---|
| 97 | |
|---|
| 98 | |
|---|
| 99 | NOTES Increasing of the 'Max. non group hits' and reducing |
|---|
| 100 | 'Min. group hits (%)' values as well as increasing of the |
|---|
| 101 | difference of the minimum and maximum values for 'Length of |
|---|
| 102 | probe', 'Temperature' as well as 'G+C content' reduces the |
|---|
| 103 | performance (speed) of the program. |
|---|
| 104 | |
|---|
| 105 | The results will be shown within the 'PD RESULT' window which |
|---|
| 106 | can be displayed by pressing the 'RESULT' button. The window is |
|---|
| 107 | automatically displayed when the probe search is completed. |
