Feature: Join adjacent alignment blocks After filtering out sequences The sequence that caused two blocks to be separate may be removed So it can be desirable to join such blocks together

Scenario: Two blocks natively in indexed access
Given indexed MAF files in "test/data"
When I query for the genomic intervals
| chrom    | start    | end      |
| mm8.chr7 | 80082334 | 80082471 |
Then 2 blocks are obtained
And the text size of block 0 is 54
And the text size of block 1 is 156

Scenario: Two blocks joined in indexed access
Given indexed MAF files in "test/data"
When I enable the :join_blocks parser option
And I filter for only the species
| mm8     |
| rn4     |
| oryCun1 |
| hg18    |
| panTro2 |
| rheMac2 |
| canFam2 |
| loxAfr1 |
| echTel1 |
And I query for the genomic intervals
| chrom    | start    | end      |
| mm8.chr7 | 80082334 | 80082471 |
Then 1 block is obtained
And the text size of block 0 is 210
