**What it does**



SNPsplit prepares tab-delimited SNP files for TRAMS. It checks each line for entries that contain multiple consecutive bases and splits them over several lines.



- **Input**: tab delimited, format: Position Ref Pol
- Position is 1-based genomic coordinate

- Ref is the reference sequence

- Pol is the polymorphism sequence



Ref en Mut sequences consisting of more than one character will be split up into separate lines. Example:



**Input**:


=== === ===

123 CGT ATG

=== === ===



**Output**:


=== = =

123 C A

124 G T

125 T G

=== = =



Bases that are the same in both columns, will be skipped. Example:



**Input**:


=== ===== ===

123 C*G*T AGG

=== ===== ===



**Output**:


=== = =

123 C A

125 T G

=== = =
