Hi!

I'm starting to use kallisto to do transcript-level expression quantification.
I have some questions:

**1)** Does `kallisto` infer the strandness of the input data just like `salmon` does (`--libType A`)? I guess the answer is no. 

**2)** For other hand, `kallisto` has the next to options:

    --fr-stranded             Strand specific reads, first read forward
    --rf-stranded             Strand specific reads, first read reverse

Are these options only working for PE data?

**3)** Regarding the fragment length estimation when using SE datasets:

    -l, --fragment-length=DOUBLE  Estimated average fragment length
    -s, --sd=DOUBLE               Estimated standard deviation of fragment length
                                  (default: -l, -s values are estimated from paired
                                   end data, but are required when using --single)

What does `DOUBLE` mean? Do we have to specify the double of the number calculated?

Thank you in advance


 1. No
 2. They should work for SE data too (never tried, though). You probably want --rf-stranded for anything remotely recent.
 3. An example of a double is `200.0` or `123.4`. That is, any number with a decimal point. The documentation there should really be changed, since I don't expect those without C/C++/etc. programming experience to know that "double" means "double precision floating point value" (or what that even means)).
