Dear all, 

When looking in the QCReport.txt files I noticed that there are gradients missing in the list of "Included gradients", which are not listed as interlace-wise check artifacts or slice-wise check artifacts (I'm skipping gradient-wise check). In fact, they are not mentioned in the report at all. This usually happens for 1-2 gradients in about 1 per 8 subjects. Does somebody know what happened to those gradients?

For example, in the file attached, you can see that gradient 42 is not listed as an included gradient and neither as an interlace-wise or slice wise artifact. 

Thanks, 
Karen
