| 1 | 87 **SnpSift filter** |
| 88 | |
| 89 You can filter ia vcf file using arbitrary expressions, for instance "(QUAL > 30) | (exists INDEL) | ( countHet() > 2 )". The actual expressions can be quite complex, so it allows for a lot of flexibility. | |
| 90 | |
| 91 Some examples: | |
| 92 | |
| 93 - *I want to filter out samples with quality less than 30*: | |
| 94 | |
| 95 * **( QUAL > 30 )** | |
| 96 | |
| 97 - *...but we also want InDels that have quality 20 or more*: | |
| 98 | |
| 99 * **(( exists INDEL ) & (QUAL >= 20)) | (QUAL >= 30 )** | |
| 0 | 100 |
| 1 | 101 - *...or any homozygous variant present in more than 3 samples*: |
| 102 | |
| 103 * **(countHom() > 3) | (( exists INDEL ) & (QUAL >= 20)) | (QUAL >= 30 )** | |
| 104 | |
| 105 - *...or any heterozygous sample with coverage 25 or more*: | |
| 106 | |

| 109 - *I want to keep samples where the genotype for the first sample is homozygous variant and the genotype for the second sample is reference*: | |
| 110 | |
| 111 * **isHom( GEN[0] ) & isVariant( GEN[0] ) & isRef( GEN[1] )** | |
