The LinearDesign program can be run with:
echo SEQUENCE | ./lineardesign [OPTIONS]
OR
cat FASTA_FILE | ./lineardesign [OPTIONS]
OPTIONS:
--lambda LAMBDA or -l LAMBDA
Set LAMBDA, a hyperparameter balancing MFE and CAI. (default 0.0)
--codonusage FILE_NAME or -c FILE_NAME
Import a Codon Usage Frequency Table. See "codon_usage_freq_table_human.csv" for the format. (default: using human codon usage frequency table)
--verbose or -v
Print out more details. (default False)
For Macbook, users may encounter a pop-up message at the first run. For Mac-M1 system, the message is:
"LinearDesign_Mac_M1.so" can't be opened because Apple cannot check it for malicious software.
For Mac-Intel system, the message is:
"LinearDesign_Mac_Intel.so" cannot be opened because it is from an unidentified developer.
If so, please go to "System Preferences -> Security & Privacy -> General" to allow LinearDesign-Mac-M1.so (or LinearDesign-Mac-Intel.so) to open.
