[ Modified from_hell.nex by 1. replacing Ns with ? so that we can use this file to test Mesquite -> cipresIDL matrix conversion (by comparing with what read_nexus_server returns). Mesquite treats N the same as ? so if the file has Ns in it it won't equal read_nexus_server matrix. 2. Mesquite was confused by {ACGT-} so I changed it to "?". (And noticied that Mesquite treats {ACGT} as N but treats N as ?). ] #NEXUS BEGIN DATA; DIMENSIONS NTAX=4 NCHAR=10; FORMAT DATATYPE=DNA MISSING=?
