Animals were sacrificed with no input from the authors (i.e. each group/facility utilized their standard method). Tissues samples were isolated from each organ, placed into an appropriate volume of RNALater, and incubated at 4C overnight. Each sample was then homogenized in a bead-mill in a phenol/chlorofom solution and RNA was isolated by and treated with DNAse on a Qiagen miRNEasy column.
Strand-specific libraries were generated using the standard RNA-Seq protocol / dUTP method, with the “second-day” done on the Beckman-Coulter SPRIworks machine. Briefly, before second-strand synthesis, samples are precipitated first and the second strand is made using a dNTP solution that replaces dTTP with dUTP. Before the final PCR step, libraries are treated with an enzyme that removes dUTP from dsDNA.

Base-calling: Illumina Real Time Analysis, scoring metric v1.5
Long-read (76-108bp libraries) were mapped with TopHat v1.1.4 with the following additional parameters: --no-novel-indels, -r [inner length], --segment-length 20, --solexa-1.3-quals, --coverage-search -g [species.gtf]
junctions from all long read (76-108bp libraries) were combined and all libraries were mapped by TopHat v1.1.4 with the following parameters: --no-novel-indels, -r [inner length], --segment-length 20, --solexa-1.3-quals, --coverage-search, -j [species_junction_file.bed] -g [species.gtf]
Cufflinks v1.0.2 was run on the long read libraries with the following parameters: --min-isoform-fraction 0.00, --pre-mrna-fraction 0.00, -g [species.gtf], --max-intron-length 100000, -u, -b [genome.fa], --library-type ff-firststrand
Transcripts from libraries within a species were combined with CuffCompare v1.0.2 with the following parameters: -r [species.gtf]
Cufflinks v1.0.2 was run on all libraries with the following parameters: --min-isoform-fraction 0.05, --pre-mrna-fraction 0.10, -G [combined_species.gtf from above], --max-intron-length 100000, -u, -b [genome.fa], --library-type ff-firststrand
Transcripts from libraries from each individual were combined with CuffCompare v1.0.2 with the following parameters: -r [combined_species.gtf]
