| 49 Basically estimates the experimental RI (RIexp) by building a RI(RT) function based on the | |
| 50 given calibration file. | |
| 51 | |
| 52 It also determines the estimated RI (RIsvr) by looking up for each entry of the given input file (Sample File), | |
| 53 based on its CAS number, its respective RIsvr value in the given global lookup library | |
| 54 (this step is also called the "RankFilter analysis" -see reference below; Sample File may be either from NIST or AMDIS). | |
| 55 This generates an prediction of the RI for | |
| 56 a compound according to the "RankFilter procedure" (RIsvr). | |
| 57 | |
| 58 Output is a tab separated file in which four columns are added: | |
| 59 | |
| 60 - **Rank** Calculated rank | |
| 61 - **RIexp** Experimental Retention Index (RI) | |
| 62 - **RIsvr** Calculated RI based on support vector regression (SVR) | |
| 63 - **%rel.err** Relative RI error (%rel.error = 100 * (RISVR − RIexp) / RIexp) | |
| 64 | |
| 65 .. class:: infomark | |
| 66 | |
| 67 **Notes** | |
| 68 | |
| 69 - The layout of the Calibration file should include the following columns: 'MW', 'R.T.' and 'RI'. | |
| 70 - Selecting 'Polynomial' in the model parameter will calculate a 3rd degree polynomial model that will | |
| 71 be used to convert from XXXX to YYYY. | |
