Basic Functions
Upload .fastq files
After logging in to the system, choose ‘Basic data’ tab, click ‘Upload fastq’. If there is no ‘Upload fastq’ button, it means the account has no remaining number of samples to upload.
After editing the FASTQ upload project name, you can choose to upload PE files or SE files by clicking the corresponding region.
If the data in one sample are divided into several FASTQ files, please switch the button below to ‘Yes’, and set the sample name of each FASTQ files in the table to help identify. Once all the files you want to upload in this batch are selected and the information is confirmed, click ‘Confirm upload’ to start uploading the files. DO NOT close this page before all the files are uploaded successfully, or you have to reupload.
A project will be created in the ‘Basic data’ tab once you started uploading FASTQ files. When all the files are uploaded successfully, you will see the project name, project ID, time you created this FASTQ uploading project, number of sample analyzed/number of total samples in this project.
There is no limitation of how much FASTQ uploading project you created. You can upload samples in different batches. If no analysis project has been created, sample data will be deleted in three months.
Create new analysis
When all the samples needed to be analyzed in one batch have been uploaded, click ‘New analysis’ button to create a new analysis project.
Select the FASTQ uploading projects and samples needed to be analyzed in this analysis project, then fill in the analysis plan. You can choose reference genome, change sample name, set groups, set comparison groups and DEG detection parameters according to your own needs.
Click ‘Save’ button to save this analysis plan in Dr. Tom. You can continue to edit the plan in ‘My report’ tab before submitting. After finishing the analysis plan, click ‘Submit Analysis’ button, Dr. Tom will run the analysis automatically.
In few hours to two days, the analysis will be finished. Click the ‘view’ button to check the analysis results.
Search
Search box on the homepage helps us to quickly locate the target genes/transcripts/proteins/DMRs/cells in the home table. In Convention mode, you can input one or more keywords (divided by space). Click the set button, you can set the logic and search scope. In Batch mode, you can search for more than IDs or symbols.
Data upload
Dr. Tom system supports to upload your own data. Click the ‘Add a project’ button after login, or the ‘upload’ button in the homepage of a project, to upload the data. Please read the file prepare guidance carefully and prepare files as required, and upload the data. If it is a new project, you are allowed to fill the analysis plan after you upload read count data successfully. Notice that you can only submit one analysis plan in one project.
Expression Data Upload Procedure
Expression file format requirement
Gene detail
Click gene ID in any table, it’ll be linked to the gene detail page, which contains the gene expression information, annotations in different databases, links to external databases, etc. Besides, Dr. Tom offers publications that have studied the corresponding genes for your reference.
Table extension
In the upper left of every table, there is an ‘Extend’ button. Click it, you can choose to add basic attribute, expression, differences among groups, annotations and information from external database to the table. Select the corresponding tag, click OK, the table will be updated.
Transfer
Click the ‘Transfer’ button on the upper left of the tables, we can find the genes that have PPI/Target/ceRNA/rnaplex/GGI/position/mapping relationship with the selected gene set.
Interactions between graphs and tables
Most of the graphs in Dr. Tom system is interactive. Select the targeted part in the graph by clicking, the right-side table will show the corresponding information. Open the tool box, we can use other analysis tools to do data visualization. The circulation of ‘graph-table-graph’ helps us to do infinite data mining.
My analysis
After we submit an analysis task using analysis tools, the task will be shown in the ‘My analysis’ list. Click my analysis, we can check all the tasks and the status. We can rename, collect, delete or check every task.
Graph setting and download
Most of the graph in Dr. Tom system can be edited. Double click the title/axis title to change the name. Click the legend to change the color. Different graphs have different setting parameter, which can be checked by clicking the setting button on the upper right of the graph. Graphs can be downloaded in JPG/PNG/SVG/PDF format.
Dataset saving
Tick to select the data, click the save button on the upper right of the table to save the dataset in this project. Click ‘My dataset’ to check saved dataset.
In ‘My dataset’, all the saved datasets can be checked. Select targeted datasets, right-side table will show the corresponding data and a Venn plot/UpsetR plot will be plotted.
Export expression file
When the analysis report is generated, users can export expression data from Dr. Tom.
Click ‘Save ID’ button on the home page to save the gene set. Then, click ‘My data set’ to check the data set list.
Select the data set you just saved, and click ‘OK’. The right-side table will show the gene details.
Switch to table view, and click ‘+ Extend’. Select the expression data (read count, FPKM or TPM) you want to exported. Click ‘OK’, the table will be extended.
Hover on the ‘Download’ button, and click the ‘Download table’ button to export the expression data.
Be aware that Dr. Tom only allows downloading tables with a row-column product less than one million. If the table contains too much content, it can be downloaded in batches.
