You are invited to an expert elicitation on metadata for LMICs 20 May at 14:15 CET
by Christa Twyford Gibson 24 Apr '25

24 Apr '25

Dear Colleagues, We are pleased to invite you to an upcoming Metadata Expert Elicitation Session on May 20 2025, at 14:15 CEST. This event is a follow-up to our engaging webinar series last fall, where a presentation on metadata sparked strong interest in further discussion—especially around applications in LMIC settings. This 90-minute session will begin with a brief introduction to key metadata concepts relevant to risk assessments, surveillance, and outbreak response. Following this, participants will join breakout discussions focused on current practices, opportunities for enhancement, and practical challenges in different contexts. The session can be joined by Zoom at: https://dtudk.zoom.us/j/67066262671?pwd=yqMv6duCXRDaSZz6ytH7hVxcV8G3U0.1 Meeting ID: 670 6626 2671 Passcode: 432088 Please email me if you would like me to add you or any of your colleagues to the meeting invite.

Reminder: SeqAfrica April Bioinformatic CoP - Hackathon Epi2Me part 2
by Pernille Nilsson 01 Apr '25

01 Apr '25

Dear Bioinformatics Community of Practice Members, We are excited to announce our upcoming Bioinformatics Community of practice session! Ousmane Sadio will be presenting his work on hacking the Epi2Me bacterial workflow pipeline. This is a fantastic opportunity to learn more about the new capabilities of the modified workflow and the process Ousmane followed to achieve these improvements. This presentation builds on Niamh's session last month, where she discussed the SeqAfrica Senegal Hackathon. Our talented team of bioinformaticians worked to adapt an existing open-source workflow to better fit the needs of laboratories new to ONT sequencing. Please note that Denmark switched to summertime over the weekend, which may have affected the timing of the CoP. Ensure you check the time to avoid scheduling conflicts. Date: Thursday 3 April 2025 Time: 12:30 CEST Zoom link: https://dtudk.zoom.us/j/68532308758?pwd=AK8CRJQaskd7BvavJZ8RapDJ63baCg.1 Meeting ID: 685 3230 8758 Passcode: 210273 We look forward to seeing you there! Best wishes, Pernille
