Hello Joe,
In my understanding, there are certain differences between the Bikram and the Barkan sequence. I’m almost sure, that one is the direct copy of the other. I am willing to be corrected on that of course, as I have personal experience with one of them only.
What I do know is that they both are Hatha and Hot Yoga. Which one have you fallen in love with?
If you enjoy practising at home I definitely recommend you have a look at Gabrielle’s manuel, the Hot Yoga MasterClass. I think you’d find it very useful 
Namaste,
Andrea
