MAKER

Getting EAD scores

Runing on Helix

  1. Create conda environment and install
cd /projects/augustold/CSHL/MAKER

conda create --name maker
conda activate maker
conda install maker
  1. Creat the control file
cd /projects/augustold/CSHL/MAKER

cat round2_maker_opts.ctl

#-----Genome (these are always required)

organism_type=eukaryotic #eukaryotic or prokaryotic. Default is eukaryotic

#-----Re-annotation Using MAKER Derived GFF3

#-----EST Evidence (for best results provide a file for at least one)

#-----Protein Homology Evidence (for best results provide a file for at least one)

#-----Repeat Masking (leave values blank to skip repeat masking)

rmlib= #provide an organism specific repeat library in fasta format for RepeatMasker
repeat_protein= #provide a fasta file of transposable element proteins for RepeatRunner

#-----External Application Behavior Options
alt_peptide=C #amino acid used to replace non-standard amino acids in BLAST databases
cpus=1 #max number of cpus to use in BLAST and RepeatMasker (not for MPI, leave 1 when using MPI)

#-----MAKER Behavior Options
max_dna_len=300000 #length for dividing up contigs into chunks (increases/decreases memory usage)
min_contig=1 #skip genome contigs below this length (under 10kb are often useless)

single_length=250 #min length required for single exon ESTs if 'single_exon is enabled'
correct_est_fusion=0 #limits use of ESTs in annotation to avoid fusion genes

tries=2 #number of times to try a contig if there is a failure for some reason
clean_try=0 #remove all data from previous run before retrying, 1 = yes, 0 = no
clean_up=0 #removes theVoid directory with individual analysis files, 1 = yes, 0 = no
TMP= #specify a directory other than the system default temporary directory for temporary files
  1. Run MAKER
#maker -CTL 
vi run_maker.sh

mpiexec -n 30 maker -base test round2_maker_opts.ctl maker_bopts.ctl maker_exe.ctl

bash ./run_maker.sh 2>&1 | tee run_maker.log
