I have a set of variants in the following format
BRAF_7_140453150_A/T BRAF_7_140453145_A/T BRAF_7_140453145_A/C BRAF_7_140453136_A/T BRAF_7_140481417_C/A
I want to extract flanking bases for each of this mutation. How do I get the strand information form the above data? I need to create a bed file with the format Chromosome start end strand.
