Over the past few months I’ve been trying to work with the HCSConnect web service API that Cellomics provides as a means to programmatically access the Arrayscan image and data store. While the API works for getting things such as plate names, I was unable to retrieve images. After much poking and some suggestions from […]
Visual pairwise comparison of distributions
While analysing some data from a dose respons screen, run across multiple cell lines, I need to visualize summarize curve data in a pairwise fashion. Specifically, I wanted to compaure area under the curve (AUC) values for the curve fits for the same compound between every pair of cell line. Given that an AUC needs […]
Python, permission and forgiveness
This morning I was writing some Python code that needed to perform lookups on a very large map. 1234mapSize = 65000 amap = {} for i in range(0,mapSize): amap[’k%d’ % (i)] = i If a key did not exist in the map I needed to take some action. My initial effort performed a […]
New version of fingerprint (3.4.9) – faster Dice similarity matrices
I’ve just pushed a new version of the fingerprint package that contains an update provided by Abhik Seal that significantly speeds up calculation of pairwise similarity matrices when using the Dice similarity method. A ran a simple comparison using different numbers of random fingerprints (1024 bits, with 512 bits set to one, randomly) and measured […]
CINF Webinar: Practical cheminformatics workflows with mobile apps
