I work in bioscience field, mainly involved in data analysis. Lately, numbers are growing and things are getting more complicated by the use of multiple analysis techniques (most of them "omics" type) on various biological samples from the same set of individuals/patients/animals.

I would like to implement a better way of locally storing data and meta-data (here I refer to meta-data as the general data about the individuals/patients/animals, but also to meta-data about instrument used in assay) which would also allow me to perform meta-analysis (mainly using R, but I would like to have a solution that can also work with SPSS). I am searching for some guides to learn the basics of building, managing and using databases, optimally tailored to biology and "omics"application.

I could summarize my situation in the following image

In summary, over the same set of samples (individual - S1 to Sn), that would be the main entry in the database, we could perform a series of experimental assays, each of which resulting in some numeric data generally organized in a csv like format with the same id, accompanied by some meta data about the assay (instrument used and similar). The creation of new entries in the database would usually be via bulk upload of those csv files.

Essentially, I would like to collect and connect everything in one place, instead of having 1 folder for every project, with related R script and raw data. From R, I would then retrieve from the general database the data relevant to a certain project, and perform a set of analyses. As of now, I am interested in a local solution, but I would like to leave the eventual predisposition for remote access open

I have no background in databases, so I am open to any solution which would better fit my needs. For example, I have read that there are relational databases and graph databases (I do have some experience with ontologies) and can't decide which would be better. Any "digested" source of general information from users who have handled similar issues, any beginner tips, or any suggestion on best solution, would be of great benefit for me to try and start something.

I'm doing animal studies and using automated operant boxes that output massive csv files, I've got multiple animals running multiple sessions per day and so in order to make sense of my data I loop through multiple csv files and extract relevant data to a separate excel file. I managed to make almost all of the the code dynamic except for one crucial bit: I have to assign subject IDs to multiple ranges of rows that correspond to that subject's data.

The way I'm currently doing it is first extracting a list of [ID]'s of 16 subjects in the order the they were run on that day and then creating a new session order column in my dataframe that tells which session the data is for. Then I've made a blank 'ID' column to which I then manually assign each range of rows from session one to the first element in the [ID] list, then the session 2 to second element and so on, here is the code example:

I just installed Ionic with

I am writing a CUDA program that will probably run on many different GPUs. I would like to know if CUDA provides some way of reading from code (either runtime or compile time) the capabilities of the current GPU, meaning the number of threads a single block can contain, and the maximum number of blocks, so I can tailor the launch of the kernel to optimally use all the resources.

I know it may sound like a silly question but I can't find any answers online.

Bonus question if it is not possible: I see here that someone says they know the Jetson TX1 has

2 SM’s - each with 128 cores. I read that per SM (which I understand there are 2) there can be a maximum of 16 active blocks, and 64 active warps (or 2048 active threads).

How can I find this info for a given GPU?

I am experiencing a scenario where my indigenous recursive implementation program output's a nested list, very similar to a tree. The nested list designed is an abstraction of a complicated structure. What I would require, is to resolve the nested list into many different rows as much as combinations available (optionally implementing recursion).

Previously I tried anytree but my needs are complicated and though good, it was not yielding to my tailored demand. Please do take into account that the nested list is multi-dimensional

My company wants to conduct a pilot to see if providing doctors with certain risk information about their patients would help them make better decisions. Before we build a full scale app, we just want to determine if the information is useful to doctors, it helps patients, and if generating the data and getting it to doctors is even feasible. Unfortunately, due to institutional data security and privacy rules, I have to use Microsoft Teams messaging to test this. Otherwise, I'd use Microsoft Access VBA, loop through a list of emails, and send the tailored information that way. However, because I won't be able to easily encrypt emails like this (and it prone to people forgetting - unless there's a way to set up encryption from MS Access VBA) I can't use MS Access/Outlook.

So bottom line, say I have a dataset with 20 emails/Teams contact information of doctors, along with unique medical information about 1 of their patients. Aside from copying and pasting the data into a message, and sending it in Microsoft Teams for each doctor, is this a more automated way to do this? Think of this as sort of a Microsoft Teams mail merge.

I have an image that has cereal items below:

The image has:

• 3 walnuts
• 3 raisins
• 3 pumpkin seeds
• 27 similar looking cereal

I wish to count them separately using opencv, I do not want to recognize them. So far, I have tailored the AdaptiveThreshold method to count all the seeds, but not sure how to do it separately. This is my scripts:

I created a Java class to decorate another interface with generics. However, it always has some compiler errors. This is the tailored sample code that could reproduce the error.

I am brand new to coding and am working my way thru the tech with tim kivy youtube turtorials. I am following his code for the most part but am trying to tailor it to the app I'm trying to develop. I am getting the following error message and have no idea how to fix it.
