Chess analysis mistake?

I sent in a game for analysis and by the 2nd move i had played the sicilian but it told me that it was an inaccuracy o.O how is that possible?

I just did an analysis last night. I guarantee it was not 2200 analysis. More like 1200. Far from perfect

Maybe this thread will help:

That tells me about the opening, i just wanted to know why the computer called the opening an inaccuracy :P

Great e ample of how computers are not perfect

Neither is my typing

I did a computer analysis in which the computer ignored a queen en prise.  In an alternative line, both players completely missed it.

Because the computer wasn't told it was a solid opening. All it can do is look ~6 moves ahead and decide if it likes its position or not using a positional evaluation based on predetermined factors, without understanding any of the ideas in the Sicilian.
