TRAPID specifications


Unique identifier OMICS_12125
Interface Web user interface
Restrictions to use None
Input data RAPID supports properly formatted multi-fasta files, with the '>' symbol indicating the transcript identifier of the following sequence. In case the headers of the multi-fasta file consist of multiple sections separated by the '|' symbol, the first section will be used as unique identifier.

[…] to accurately quantify expression levels reducing biases between conditions and samples (trapnell et al., ). the completeness and quality of the assembled transcriptome was assessed with busco and trapid (simão et al., ; van bel et al., ). differentially expressed transcripts between treatments were identified with cuffdiff 2.1.1 (default parameters plus—multi‐read‐correct […]

[…] srr2952867) using trinity (). to examine the quality of assembled transcripts, we predicted the open read frame (orf) for all transcripts and translated them into protein sequences using the program trapid ( to further eliminate the data bias caused by low quality transcripts, only the transcripts that are more than 300 amino acids in length […]

[…] due to the intrinsic limitations of this benchmark with species with complex polyploidy (simão et al., ) and the senescent nature of the material, representing very specific tissue and conditions. trapid (van bel et al., ) provided an assessment of transcripts structure and completeness, by comparing transcript length to the lengths of its associated gene family. with an average sequence […]
