+File containing isoform level expression estimates. The first line

Fields are separated by the tab character. Fields within "[]" are only
-presented if '--calc-ci' is set. pme stands for posterior mean
-estimation. pmc stands for posterior mean counts. ci_lower_bound(l)
-means the lower bound of the credibility intervals, ci_upper_bound(u)
-means the upper bound of the credibility intervals. So the credibility
-interval is [l, u]. 'transcript_id_list' is a space-separated list of
-transcript_ids belonging to the gene. If no gene information is
-provided, this file has the same content as
-'sample_name.isoforms.results'.
+presented if '--calc-ci' is set.
-=item B<sample_name.isoforms.results>
+'transcript_id' is the transcript name of this transcript. 'gene_id'
+is the gene name of the gene which this transcript belongs to (denote
+this gene as its parent gene). If no gene information is provided,
+'gene_id' and 'transcript_id' are the same.
+
+'length' is this transcript's sequence length (poly(A) tail is not
+counted). 'effective_length' counts only the positions that can
+generate a valid fragment. If no poly(A) tail is added,
+'effective_length' is equal to transcript length - mean fragment
+length + 1. If one transcript's effective length is less than 1, this
+transcript's both effective length and abundance estimates are set to
+0.
+
+'expected_count' is the sum of the posterior probability of each read
+comes from this transcript over all reads. Because 1) each read
+aligning to this transcript has a probability of being generated from
+background noise; 2) RSEM may filter some alignable low quality reads,
+the sum of expected counts for all transcript are generally less than
+the total number of reads aligned.
+
+'TPM' stands for Transcripts Per Million. It is a relative measure of
+transcript abundance. The sum of all transcripts' TPM is 1
+million. 'FPKM' stands for Fragments Per Kilobase of transcript per
+Million mapped reads. It is another relative measure of transcript
+abundance. If we define l_bar be the mean transcript length in a
+sample, which can be calculated as
+
+l_bar = \sum_i TPM_i / 10^6 * effective_length_i (i goes through every transcript),
+
+the following equation is hold:
-File containing isoform level expression values. The format of each
-line in this file is:
+FPKM_i = 10^3 / l_bar * TPM_i.
+
+We can see that the sum of FPKM is not a constant across samples.
+
+'IsoPct' stands for isoform percentage. It is the percentage of this
+transcript's abandunce over its parent gene's abandunce. If its parent
+gene has only one isoform or the gene information is not provided,
+this field will be set to 100.
+
+'pme_expected_count', 'pme_TPM', 'pme_FPKM' are posterior mean
+estimates calculated by RSEM's Gibbs sampler. 'IsoPct_from_pme_TPM' is
+the isoform percentage calculated from 'pme_TPM' values.
+
+'TPM_ci_lower_bound', 'TPM_ci_upper_bound', 'FPKM_ci_lower_bound' and
+'FPKM_ci_upper_bound' are lower(l) and upper(u) bounds of 95%
+credibility intervals for TPM and FPKM values. The bounds are
+inclusive (i.e. [l, u]).
