Tax treatment on capital loss due to investment in a startup

Hi all, 

I had done a small investment in a startup in 2015 in terms of convertible note without any interest. The startup had to shutdown for some reasons in FY 2016-17. So, I incurred a total loss of capital. 

For FY2016-17, I have some short term capital gains from investments in equity. Can I set off my loss in convertible note against this and carry forward the remaining loss for next few years? 

Thanks in advance.
