# Pattern Training Information Strings

When you train a pattern using PatMax, PatMax may provide diagnostic information about the pattern in the form of text strings. The following table describes the messages that PatMax can produce at training time:

Information Strings Messages | Notes
--- | ---
10000: Pattern may contain too few features. | PatMax did not detect enough features to train a reliable pattern. Examine the trained feature display.
10001: Difficult to choose feature granularity; manual override may be desirable. | Examine the trained feature display. This message is only returned if you have configured PatMax to determine feature granularity automatically.
10100: Pattern may be less accurate than expected because the training pattern appears blurry. | PatMax trained a pattern, but because the pattern was blurry, the accuracy of alignment results may be reduced. This message is only returned if you are training a pattern using the PatMax algorithm.
10101: Pattern may contain insufficient information to measure DOF reliably. | The trained pattern is potentially confusing in the indicated degree of freedom. See the topic on Image Training for information on confusing patterns.
10102: Pattern is degenerate. The results will probably be unstable because all of the coarse granularity boundary points have the same direction. | At the coarse granularity limit, all of the feature boundary points have the same orientation. Examine the trained feature display.
10200: Pattern may run slowly due to predominance of fine features; manual override may be possible. | Because of a large number of small features in the pattern, alignment may take more time. Try manually specifying a larger coarse granularity value.
