Priapulus profiling in situ matching

Warning: preg_match_all(): Compilation failed: invalid range in character class at offset 7 in /home/customer/www/ on line 77

I got some in situ pictures from Priapulus and  tried to match them to the staged expression levels data. They are congruent more or less, although it is not so straightforward since stage pictures is not complete (early/late missing) and embryos are not exactly the specific rna stages.

However, I can see gastrulation as a major burst of expression for most of the genes we have the in situs.
