This readme should help you get started with, which is for TE annotation

Setting up -------------------------------------------------------------------

i) Using is a program that post process the xm output file of RepeatMasker.

ii) Usage -fasta -LTR -classi -gene

Command line example : -LTR clariTeRep_LTRposition.txt -gene v443_0001.annoGene.embl -classi clariTeRep_classification.txt -fasta v443_0001.fas -dir [your directory] v443_0001.fas.out.xm


To recap, requires:

  • the output file .xm from RepeatMasker
  • a tabular file containing the classification of the library use in RepeatMasker :
  • a tabular file containing the position of the LTR retrotransposons present in the library
  • embl file containing the gene annotation of the sequence (in triAnnot format).
  • a FASTA-format file containing your query sequence (multi-FASTA file is not accepted)

iv) Input FILE

1) xm output file from RepeatMasker

example :

1725 20.7 2.6 0.8 v443_2791 5 393 (40687) C ctgB_rep_0246#Unknown (7481) 396 1 * 4791 21.8 0.8 3.3 v443_2791 378 1704 (39376) + ctgF_rep_0077#Unknown 322 1615 (7557) * 5649 11.4 0.4 0.4 v443_2791 799 1704 (39376) + ctgF_rep_0055#Unknown 722 1627 (11086) 15719 9.1 0.5 0.7 v443_2791 6858 9147 (31933) + ctgF_rep_0055#Unknown 5829 8115 (4598) 9263 22.2 0.9 2.8 v443_2791 7600 9932 (31148) + ctgF_rep_0077#Unknown 2241 4528 (4644) *

2) Tabular file of the classification

example :

sequenceID family

TREP100 RLC_famc1.1 TREP1000 DTT_famn14 TREP1001 DTT_famn1

3) Tabular file of the position of LTR in the LTR retrotransposons Note : the total number of LTR retrotransposons is not obligated to be present in this file.

example :

sequenceID family LTRtype start end

ctgH_rep_0307 RLG_famc3 LTR5 1 3945 ctgH_rep_0307 RLG_famc3 LTR3 7931 12091 sr2_rep_0226 RLC_famc9 LTR5 1 214 sr2_rep_0226 RLC_famc9 LTR3 4972 5185

4) Gene annotation in EMBL format TriAnnot Note : only the locus_tag and the id is require to run, other tag (such as blastp_file...) are not necessary.

example :

ID unknown; SV 1; linear; unassigned DNA; STD; UNC; 1411106 BP. XX AC unknown; XX XX FT CDS join(141960..142006,142121..142147,142248..142370,142493..142739,142850..142873) FT /locus_tag=v443_0002_EXONERATE_BLASTX_protOSA_6 FT /blastp_file=v443_0002_EXONERATE_BLASTX_protOSA_141960_142873_Q5JM42_Match_0005_mRNA_CDS.bltp FT /id=v443_0002_EXONERATE_BLASTX_protOSA_141960_142873_Q5JM42_Match_0005_mRNA_joinedCDS FT /note=Similar_to: hypothetical_protein FT /note=BestBlastHit: B9EZI3_ORYSJ TrEMBL databank Putative uncharacterized protein - %25id: 91.67 - hcov: 13.78 - qcov: 100.00 FT /note=Status: High Confidence FT CDS complement(join(143435..144154,144239..144363,145030..145267)) FT /locus_tag=v443_0002_EXONERATE_BLASTX_validated_9 FT /expressed FT /blastp_file=v443_0002_EXONERATE_BLASTX_validated_143435_145267_AFR_02_CAT01_3_Match_0001_mRNA_CDS.bltp FT /id=v443_0002_EXONERATE_BLASTX_validated_143435_145267_AFR_02_CAT01_3_Match_0001_mRNA_joinedCDS FT /note=Similar_to: putative_function - F2CSA4_HORVD TrEMBL databank Predicted protein OS Hordeum vulgare var distichum PE 2 SV 1 FT /note=BestBlastHit: F2CSA4_HORVD TrEMBL databank Predicted protein - %25id: 96.12 - hcov: 100.56 - qcov: 100.00 FT /note=Function_coverage: 94.71 FT /note=Function_identity: 97.94 FT /note=Function_target: F2CSA4 22 361 FT /note=Status: High Confidence

5) FASTA file Note : only one sequence could be contained it the FASTA file, multi fasta file are accepted

AUTHOR: Josquin Daron (INRA Clermont-Ferrand)


This script is used to post process a embl output of RepeatMasker

USAGE: -fasta -LTR -classi -gene

   ### OPTIONS ###

   -h|--help:             print this help
   -LTR:                  tabulation file of the LTR annotations
   -classi:               corresponding file sequence id to family id
   -fasta:                fasta file of the annotated sequence
   -gene:                 embl file of the gene annotation
   -dir:                  directory name
