* If there is time we can get hold of the original FASTQ file and perform statistical tests on it.  And you can attempt statistical imputation to infer missing SNPs. Idea behind imputation is like what we do in electronic engineering when we do error correction in digital communication systems.  For example if a communication system transmits the sentence "the cat sat on the mat"  and we receive "th* c*t s*t *n th* m*t" with drop outs in information, we can still reconstruct the sentence.  You can think of a DNA file as being like a long message that also suffers drop outs, and so you can use statistical techniques to infer values. We electrical engineering we call this "error correction" but in bioinformatics this is called "imputation."
