NeoChr
NeoChr module would assist users to grab related genes in different pathways manually, to rewire genes’ relationship logically*, and to replace genes with ortholog that score higher*. Firstly, it would allow users to define gene order and orientation in DRAG&DROP way. Secondly, decoupled these genes if have overlap and make all genes are non-redundancy. Finally, add chromosome features to build a new chromosome and show in the JBrowse. Moreover, users can drag a window in the JBrowse and delete any gene in the window.
Note:
*These function are unavailable now, please wait for version 2.
**You can also add any thing here including your own water mark.
Plugin Scripts
This module contains three plugins: Decouple.pl, Add.pl and Delete.pl.
1.1 Decouple.pl
This plugin is to decouple the genes which have overlap gene regions. These overlapping genes can be decoupled if meet the following conditions: (1)If two genes have overlap gene regions, the latter gene 5’UTR does not cover the former gene initial codon (ATG); (2)Overlapping region initial coordinate is in the coding DNA sequences(CDS) of gene which is need to be decoupled; (3)The decouple site of CDS have synonymous substitute codon to replace; After decoupling, we use these non-redundancy genes to generate a GFF file and a FASTA file.
1.1.1 Internal operation
First, this plugin extracts base sequence from the genome file according to the gene order list, and records the gene order in the list. And then plugin records the annotation information according to the specie GFF file, moreover, plugin extends gene CDS upstream 600bp as 5’-UTR and downstream 100bp as 3’-UTR if the GFF file does not contain annotated these two features.
Second, this plugin detects the overlapping genes in the same chromosome. In case the overlapping genes are detected, it will judge whether the overlapping initial site is located in the CDS region, and identify the site is belong to phase0/1/2.
Third, the plugin attempts to synonymous substitute codon to break the initial codon intra the CDS. Printing information whether or not be decoupled successfully, such as:
And non-redundancy genes are generated.
Finally, the plugin links non-redundancy genes to construct a new chromosome according to the gene order.
1.2.1 Example
We have two input forms to execute the plugin:
1. Using string format as gene order list input form:
perl GeneDecouple.pl --species saccharomyces_cerevisiae_chr --list_format string --gene_order="YAL054C -,YAL038W +,YBR019C -,YBR145W +,YCL040W +,YCR012W +,YCR105W +,YDL168W +,YPL017C -,YIL177C -,YIL177W-A +,YIL172C -,YIL171W-A +,” --geneset_dir ../gene_set --upstream_extend 600 --downstream_extend 100 --neo_chr_gff neochr.gff --neo_chr_fa neochr.fa
2. Using file format as gene order list input form:

NucleoMod
NucleoMod can modify CDS based on synonymous mutation. It has 5 applications. Firstly, NucleoMod is used to design CRISPR sites on NeoChr so that we can silence the wild type genes. Secondly, it can erase specific enzyme sites according to the users' selection. Thirdly, users can create an enzyme site in selected region of specific genes. Fourthly, it can optimize the codon efficiency to increase the expression level. Finally, it can smash the tandem repeat bases to reduce the synthesis difficulty.
Plugins
This module contains 5 plugins: CRISPR design, erase enzyme site, create enzyme site, codon optimization, repeat smash. All plugins are included in the main program.
2.1 CRISPR design
This plugin is used to design CRISPR site of NeoChr genes so that we can silence the wild type genes. We use blast+ to ensure the uniqueness of CRISPR sites. If you are using more than one plugin at the same time, this plugin will start firstly and deliver the data to next plugin. Otherwise it will generate a new fasta file for sequence and gff file for annotation.
2.1.1 Internal operation
First, this plugin extracts sequence and annotation from the NeoChr FASTA file and GFF3 file, respectively. Regular expression will be applied to find the 23bp basic structure of CRISPR site, with a head of ‘G’ then following 20 facultative bases and finally followed by ‘GG’. All the sequences and locus will be record in an array.
Second, the blast+ will be used to check whether the 12bp sequences (from 9th to 20th) are uniq in the wild type genome. Only uniq sites will be reserved.
Third, synonymous substitution method will be applied to change one base between the 9th to 20th bases of the CRISPR structure. The result will be record in GFF as an element of gene. If –verbose is set, the designed number will be report in STDOUT.
Finally, if this plugin is the last module, the sequence and annotation information will be recreated in FASTA and GFF format.
2.1.2 Example
We have two input forms to execute the plugin:
Run CRISPR design plugin only:
perl NucleoMod.pl -inputfa NeoChr.fa -inputgff NeoChr.gff -outputgff new_annotation.gff -outputfa new_chr.fa -crisprnum 2 -database saccharomyces_cerevisiae_chr.fa

2.2 Erase enzyme site
Given a list of restriction enzyme information, this plugin will erase the restriction sites in every gene. If you are using more than one plugin at the same time, this plugin will start after CRISPR design and deliver the data to next plugin. Otherwise it will generate a new fasta file for sequence and gff file for annotation.
2.2.1 Internal operation
The enzyme information will be extracted. (If the –borbrickstandard parameter is set, it will also remove EcoRI, XbaI, SpeI, PstI and NotI) The recognize site will be reformatted to regular expression and searched in the CDS regions. Once a restriction site is matched, synonymous substitution method will be applied to try to erase the enzyme site. When the substitution is finished, the plugin will restart the next search from 1 base after the last matched position. If this plugin is the last module, the sequence and annotation information will be recreated in FASTA and GFF format.

SegmMan
This module will cut chromosome into pieces with different sizes with Gibson, Goldengate, Homologous adaptors to them so that they are able to be assembled into whole experimentally.
Plugin Scripts
3-1. 01.whole2mega.pl
This utility can split the whole chromosome ( at least 90kbp long ) into about 30k segments and add homologous overlap and adaptors, so that these fragments can be integrated into whole experimentally.
Internal operation
First, this utility searches for the location of centromere and ARSs (autonomously replicating site). The minimal distance between centromere and ARS should NOT be larger than a defined megachunk which is about 30k long.
Second, this utility cuts out the first 30k sequence window containing the centromere and its adjacent ARS, and then adds this megachunk with two original markers and left, right telomeres.
Thirdly, this utility continues to cut more megachunks from the original one to both ends. But these megachunks are not independent, they all have about 1kbp overlaps. Moreover, these new splited window can be given only one marker alternately and only left or right telomere.
The output file will be dealed with 02.globalREmarkup.pl
