FishCODE has detected that you chose to combine samples of different species. The current platform does not support such analysis operations. The platform will clear the list of samples you originally selected in the "Selected build-in samples" section and add your newly selected samples.
Click "Confirm" in the lower right corner to confirm this operation, or click the "Cancel" button to cancel this operation.
Please note that unchecking this checkbox means you do not need to check the built-in data for analysis, FishCODE will clear any samples you have selected in the "Built-in datasets selectors" section.
Note that unchecking this checkbox means you don't need to leverage built-in data for analysis. FishCODE will clear all samples you selected in the "Built-in datasets" section.
Click "Confirm" in the lower right corner to confirm this operation, or click the "Cancel" button to cancel this operation.
Please note that unchecking this checkbox means that you will not use the data you upload for analysis. FishCODE will clear any data you uploaded in the "User's Own datasets" section.
Click "Confirm" in the lower right corner to confirm this operation, or click the "Cancel" button to cancel this operation.

Quick start 1. Video
This video (we strongly recommend that you watch this tutorial before using it!) vividly demonstrates the use of online methylome analysis with built-in data support. Given the step-by-step nature of the tool, users can follow the video to recreate the operation. You can also get a detailed description in the "HELP -> Usage -> Methylation analysis" section.
Quick start 2. Processing flow
Users need to pay attention to three points when conducting online analysis in the direction of the arrow. 1. Samples cannot be selected across species, and it is not recommended to combine RRBS and WBS for analysis. 2. Batch effect removal is also optional. 3. The email address is optional, but we recommend that you fill it in. FishCODE will send the analysis results to the email address you specify. Regardless of whether you fill in your email address,we will give you a URL to the results page.
Feature 1. Rich built-in data
We provide online methylation differential analysis supported by omics data. Users can combine FishCODE's rich built-in methylation data (61 data sets containing 1419 samples) with their own data to perform combined analysis with a high degree of freedom. These omics data covering a wide range of experimental conditions can also be freely explored individually.
Feature 2. DMRs/DEGs and corresponding visualization
This part not only supports global DMR search, but also performs annotation of DMR-associated DMGs by default. It is worth noting that users can visualize DMRs by clicking on the beginning of the row of DMRs on the task results page provided by FishCODE, or click on the gene column annotated in the row to jump to the detailed information page of the gene. example url
The adjustment panel will be automatically cleared When the user switches between different types of pictures for fine adjustment:
The adjustment panel will be automatically cleared When the fine-tuning button is clicked each time:
A. This means that FishCODE did not detect the required user input or/and built-in data. B. This means that FishCODE did not detect that you uploaded a suitable experimental design form (“Design experiment” part) C. This means that FishCODE detects that the table in your "Design experiment" section is not sufficient (2 * 1), at least two groups and each group must have at least one samples.
Yes, the annotated genes of DMRs will be given by default in FishCODE result emails and results pages. Users can set upstream and downstream gene distance limits in the "Analysis parameters" --> "Distance of associated genes" section. It is worth noting that the distance between upstream and downstream genes is optional, but genes containing DMRs are given by default.
Ajax on the result page automatically refreshes the page status. If your email has received the result, or the status has reached the last step normally, if there is still no result displayed on the page, just wait for a few seconds.
This visualization utilizes the JBrowse2 plug-in, and the task temporarily generates the corresponding visualization files of DMRs in gff format. Although we chose the most common sorting and indexing software to ensure the normal operation of this step, we do not rule out that some chromosomes cannot be sorted normally by gff3sort.pl, such as West African lungfish. If the visualization is abnormal, but the results are normal, you can use it with confidence.
(make sure to arrange at least two different groups, and each group should has at least one sample, for detailed operation, please watch this video)
(you can choose built-in data or upload your own data, or both for joint analysis, for detailed operation, please watch this video)
Note: Only highlighted lines will be added.

Protein Domain Prediction
The gene protein sequences entered by the user are aligned with the Pfam-A.hmm data, and then the alignment results are visualized based on the R package drawProteins.

Selecting ways to treat potential batch effects:
Note: within the same dataset, we recommend the option.
Note: FishCODE handles data from different sources as covariates

and is significantly less correlated with batch processing than
Note: FishCODE will automatically check the principal components that meet the user-set parameters (the proportion of interpretation of the principal components and the significance P value related to the batch effect). If there are any, they will be removed. Otherwise, the removal operation will not be performed.
[Optional] The email for receiving results :
Note: we recommend that you fill in this email so that FishCODE can send the result file to the designated email address. Of course, this is not necessary. The email is just to inform you more effectively that the running results have been completed.
[URL] The url address of your task:
Note: we recommend that you bookmark this URL address. Compared to email transmission, this page provides the function of visualizing and annotating gene connections of DMRs and DMGs, and you can also download the result file.
DE Analysis
Online differential gene analysis output results include downloadable differential analysis result files and online tables (list of up-regulated and down-regulated genes), as well as online editable visualization images and corresponding ggplot2 object files (as shown on the right), these images include sample pca Analysis visualizations, volcano plots of differential results, and heatmaps of the most significant top x genes all/up/down.
Special attention:
Classic Statistical Analysis
The user only needs to enter the data and simply select whether to add error bars and perform significance analysis to automatically get a graph (bar or box plot) with error bars and significance markers. Of course, the user can also specify which groups are to be subjected to the statistical test from the beginning step by step.

Heatmap Drawing
