P{GAL4}grn05930-GAL4 (/reports/FBti0130082.html) is a P{GawB} insertion.
FBrf0190291 says "grnGAL4 was generated by P element conversion of grnlacZ as previously described (St Pierre et al., 2002)".
That paper says "Conversion of PlArB in rn89 to PGawB was carried out as previously described (Sepp and Auld, 1999) with some modifications."
Most GAL4 enhancer traps are P{GawB}, so this makes sense.
Can you rename the insertion P{GawB}grn05930-GAL4? It's in a stock we got from Stefan Thor.
