I folded the first 8999 nt of mRNA DCR1-T1 (NM_030621). Unlike for foldings of complete mRNA sequences, mfold does not provide any results but produces the warning 'Warning! Structure Plots Missing'.

Same situation for sequences DCR1-T2 and HIV-1 vector pNL4-3 (AF324493).

Any help in generating the structures for my sequences is appreciated.

Cheers
Simon
