This shows the fails when I compare signatures from PRONOM report files with DROID signature file v79.

A little background:
In siegfried, signatures are lists of frames. Frames enclose patterns. Frames tell you where to test, patterns perform the test.
The test output below shows the text printout of failing signatures. Within the parentheses, pipes separate each frame. 

In the first example, the "F" means it is a fixed frame. This implies a fixed offset from either the BOF (B) or EOF (E). The first example is therefore at a fixed offset of 0 bytes from the BOF. The enclosed pattern is a sequence (seq) of 4 bytes. The frame that follows is also a fixed frame (F) but it is anchored to the previous frame (P), not to the BOF. In EOF segments you will see frames to the left of the EOF frame are anchored to their succeeding (S) frames. 

The last frame in the test output below is a WW which stands for window. In the example below, it should be a window of between 0 and 16000 bytes from the EOF. The DROID signatu
