tabix multipule regions with delimited between output regions

[ekushele]

Hi,

Say I have a bed file, file.bed, and I want to retrieve multipule regions.
file.bed:

chr1    10468   10469   
chr1    10470   10471   
chr1    10483   10484   
chr1    10488   10489   
chr1    10492   10493   
chr1    10496   10497 

running tabix file.bed chr1:10468-10490 chr1:10478-10490 chr1:10496-10497 gives me all the rows that matches region in the file.bed:

chr1    10468   10469  
chr1    10470   10471  
chr1    10483   10484  
chr1    10488   10489  
chr1    10483   10484  
chr1    10488   10489 
chr1    10496   10497 

Can I have an option to separate between the results, i.e. to define which rows came from each region? Something like:

chr1    10468   10469  
chr1    10470   10471  
chr1    10483   10484  
chr1    10488   10489
  
chr1    10483   10484  
chr1    10488   10489 

chr1    10496   10497
