Bispecific that won't render

[AndrewCRMartin]

VH.a(1:5)-CH1(2:6)|VL.b(3:8)-CL(4:9){1}|
VL.a(5:1)-CL(6:2)-L(7)-VH.b(8:3)-CH1(9:4){1}-H(10:18){2}-CH2(11:19)-CH3(12:20)|
VL.a(13:21)-CL(14:22)-L(15)-VH.b(16:23)-CH1(17:24){1}-H(18:10){2}-CH2(19:11)-CH3(20:12)|
VH.a(21:13)-CH1(22:14)|VL.b(23:16)-CL(24:17){1}

Drawing this one creates the correct AbML (although somewhat different from this hand-created version), but it won't render.

Is this the intended result? It's stored in the library as a Fab-IgG.

I think the issue with getting the expression is that it's issue is getting the chains mixed up. I'll take a look.

Yes that's it. Not sure why my version didn't render (even when drawn and then Tidy'd

The following version (without a linker) doesn't render either:

VH.a(1:5)-CH1(2:6)|VL.b(3:7)-CL(4:8){1}|
VL.a(5:1)-CL(6:2)-VH.b(7:3)-CH1(8:4){1}-H(9:16){2}-CH2(10:17)-CH3(11:18)|
VL.a(12:19)-CL(13:20)-VH.b(14:21)-CH1(15:22){1}-H(16:9){2}-CH2(17:10)-CH3(18:11)|
VH.a(19:12)-CH1(20:13)|VL.b(21:14)-CL(22:15){1}

I see the issue. The heavy chains start with a VL domain and that's confusing the step that sorts the chains out. I'll take a look
