MetamORF ORF ID The MetamORF ID of the ORF. This is an unique ID referring to the ORF.	ORF length The genomic length of the ORF (in bp). This length is defined as the sum of the lengths of each exon constituting the ORF (thus excluding its eventual introns) and includes both the start and the stop codons.	Nucleic sequence The nucleic sequence of the ORF.	Amino acid sequence The amino acid sequence of the ORF.	Identification The method of identification used to identify the ORF. MetamORF currently integrates data from three main type of identification methods: bioinformatic predictions, ribosome profiling experiments and mass spectrometry experiments (either proteomics or proteogenomics). See the data sources section of the advances documentation for more information about this.	Start codon The start codon sequence of the ORF.	Kozak context The Kozak context computed by our algorithm for the ORF on the transcript. See the Kozak contexts section of the advanced documentation for more details regarding the nomenclature we use.	Exp. count The number of original datasets that identifed the ORF on the transcript.	Data sources The data sources in which the ORF has been identified. Click on the button to display all the original IDs in a pop-up. See the data sources section of the advanced documentation for more details regarding the information related to the data sources and the original ORF IDs.	ORF annotations A comma-separated list of the annotations computed by our algorithm for the ORF on the transcript. See the section dedicated to ORF annotations in the advanced documentation for more details regarding the nomenclature we use.	Cell types A comma-separated list of the cell types in which the ORF has already been identified on the transcript.

MetamORF transcript ID The MetamORF ID of the transcript. This is an arbitrary ID that does not correspond to any official (Ensembl, NCBI...) transcript ID or external reference.	Transcript ID The official transcript ID (usually an Ensembl ID, e.g. ENST00000395565).	Transcript name The transcript name (e.g. MDK-202).	Transcript biotype The biotype of the transcript (as defined by Ensembl).	Identification The method of identification used to identify the ORF. MetamORF currently integrates data from three main type of identification methods: bioinformatic predictions, ribosome profiling experiments and mass spectrometry experiments (either proteomics or proteogenomics). See the data sources section of the advances documentation for more information about this.	Kozak context The Kozak context computed by our algorithm for the ORF on the transcript. See the Kozak contexts section of the advanced documentation for more details regarding the nomenclature we use.	Exp. count The number of original datasets that identifed the ORF on the transcript.	Data sources The data sources in which the ORF has been identified. Click on the button to display all the original IDs in a pop-up. See the data sources section of the advanced documentation for more details regarding the information related to the data sources and the original ORF IDs.
