Project Planning
Project Planning
Data analysis is crucial for any NGS project and we recommend advance planning. For researchers needing bioinformatics support from us, we strongly encourage you discussing of your projects with us at an early stage of project planning so as to evaluate feasibility and set proper expectations.
What to expect
Our FREE consultation will help you decide on the choices of sequencing technology (see table below), length of read, throughput required (amount of coverage) and analysis methodologies etc. All of these will play an important role in answering your specific scientific questions. Below table lists some of the typical projects with suitable technologies, but we may discuss any other. Contact us NOW to discuss your project!

Data Collection Overview
From 1-Jun-2022, to facilitate CPOS users to collect data 24/7, all data will be available to collect via sFTP server. The service of data transfer directly to CPOS HPCF directories, which is only available in office hours, will be discontinued. For all users, data could be downloaded via sFTP server following the workflow below.
- Once data is available, users will be notified via email.
- User receives sFTP username and password through email, unzip password will be provided in a separate email.
- User downloads data from sFTP server (see instructions below).
- To unzip files, user can use 7zip or winrar.
In compliance with the centre’s data protection scheme, analysed data are compressed and encrypted prior to delivery via sFTP server. Username and password to access sFTP server and password to unzip files are provided in separate email for added security. Data could be unzipped using 7zip or winrar. Due to limited server hard disk space, data will only be kept for 1 month after delivery. Data will then be removed from our servers without prior notice. Please ensure that you keep a copy of the data (analysis results and all intermediate files) securely and clearly identified for future reference.

Along with the analysis pipelines developed at CPOS, we have also accumulated resources that are useful for various types of data analysis. To facilitate other fellow bioinformaticians, these resources will be available through this website.
Exome Target Regions
The BED files were generated by merging the target and probe regions (provided by vendor), followed by adding 200bp padded region (100bp upstream and 100bp downstream). Conversion from hg19 to hg38 was done using Batch Coordinate Conversion (liftOver) from UCSC Genome Browser Utilities. The workflow is shown as below: The padded combined regions in BED format can be downloaded by clicking the links below:

Terms of Service
At the CPOS, we strive to apply the most suitable analysis methods to your dataset and that every analysis step is carefully planned before the start of the project. As CPOS provides free consultations which include advice on suitable analysis methods and tools, we urge users to discuss with us in advance. We will in good faith provide our advice based on our expertise, yet cannot be held fully liable for the most suitable analysis method. Agreement should be reached between CPOS analysis team and the project principle investigator with good mutual understanding to allow the sharing of responsibility.
Data Handling
All data is stored on networked storage drives with periodic back-ups but CPOS will not be responsible to store the data indefinitely. All data (raw data, analysis results and all intermediate files) housed by the CPOS Bioinformatics Core may be subject to deletion 1 month after data delivery to users without prior notice. Users are advised to keep a secure, clearly identified, permanent copy of the dataset.
Acknowledgement / Authorship
We appreciate your acknowledgement of the Centre for PanorOmic Sciences (CPOS) in your publications with data generated at our centre. Authorship is deem suitable if significant intellectual input is provided. Proper recognition documents the impact of our work and helps justify the continuation of subsidized services.
