if you don't know what sample prep protocol was used you have to map your reads to a reference genome and look at the sam flags in the bam file. If it is stranded, flags 83, 99, 147 and 163 have the same abundance but in stranded, 2 of these 4 will disappear when you look at either sense or antisense genes only.
Is my RNA-Seq data stranded?
Further, library preparation protocols for RNA-Seq can be stranded or unstranded. In unstranded libraries, no information is preserved about the original transcript orientation.
How do you quantify RNA-Seq data?
The simplest approach to quantifying gene expression by RNA-seq is to count the number of reads that map (i.e. align) to each gene (read count) using programs such as HTSeq-count.
