So helpful! but i have questions, how can you view the plot of the Box Cox?
How so? You mean the histogram for the transformed data?
@@bioinfotips the same question
If I understood the question, just plot the histogram of the transformed data.
Hello Dear, please guide how to analyze this data. foreaxmple how to analyze the left-y-axis data separately then right-y-axis data? and how to add the significance pairwise?
Hi Kam. You need to have 2 separate graphpad datasheets, analyse them separately, and then, make the graph as in the video.
How to install colour deconvolutation ? Its not present in the image j applications
Do you have images Fiji? I'm pretty sure I did not had to install anything in mine.
@@bioinfotips ok. Actually I had image j. Would you kindly explain how to calculate the staining intensity not the percentage area.
Sure. Basically, you do the same thing but on the "measurements" menu, go to "set measurements" and make sure the "intesnsity" ones are checked
Hi! great video, do you have a tip for meassuring the area of cell migration of the spheroids?
Hi Juan. You mean like expansion of the spheroids? If that's the case, probably measuring the area before and after the cell migration should do it.
Thank you, really helpful !! but my data is still not following a normal distribution :(
Have you tried any of the other transformations? Like log?
Goat, thank you so much
Ahaha thank you so much. Glad I could help you
You’re greatest men
No problem 😁 hope you have fantastic results!
Hi! a very informative video. I would like to know if there's a way to do a densitometric analysis which would showcase the clustering ability of the cells. thanks!
Hi. Thank you. You mean the pixel density?
@@bioinfotips I'm working with cells overexpressed with a certain protein which makes them cluster more than the control cells. From visual interpretation I can tell my protein of interest is resulting in a higher cell-cell adhesion. So my question is, how do I quantify that? The control cells have many blank spaces in between which the mutant doesn't have
In that case, I think you can try to measure the area of the sferoid with the wand tool, so it quantifies all the continuous area, after thresholding the image. Just make sure you use the same threshold value for every image. Let me know if that works.
@@bioinfotips thanks!! This helps. Got what I wanted and glad to see my hypothesis is working. Have a great day ahead!
Haiii do you know how to count ic50 of two drug that non constant??? Please anybody enlight me if you have the solutionssss... Thxx
Hi :) what do you mean by non constant?
The ratio of two drugs is non constan
only onw collum is appearing to be analyzed, how to solve?
How so? Can you leave a print screen or send it to bioinfotips@gmail.com?
Thanks
You welcome 😁
Hello. Thank you for the video. How could I make a graph for the IC50 using graphpad prism?
When you do the analysis it automatically plots a graph for you in the graphs section. Check it and let me know if you found it.
what is value of lambda in this tutorial?
I didn't check it but I believe you can do it in the analysis menu and crosstabs statistics.
Thanks a lot. This is very helpful to me. I am currently plotting two bar graph with lije graph. I would like to learn how to do one way ANOVA .
Hi Rob 😁 check this video from the channel: czcams.com/video/hyLGYO7XV_w/video.html Let me know if that helps.
thanks for the video! however i dont understand what shall i do if the curve doesnt touch the x-axis. may you please suggest what should be done in such scenario ?
You welcome. Thank you for your question. However, I don't see a scenario where that happens... Can you send a print screen?
Well thanks! that was so much helpful!
Glad I could helpt! That means a lot to me 😁
Hi dear. How can I identify the most gender-associated flavour? I mean, I would like to know if, for example, mint is the favourite flavour of girls.
Hi :). In that case, I would recommend you to separate analysis just for girls, using maybe a ANOVA, depending on if you want to count the number of girls who have mint as the favorite flavor or if you ask to rank the flavours
Can u send the software
You can get it here imagej.net/software/fiji/downloads
What's the difference between 3 parameters and four parameters? And when should u use either of it?
Sorry for taking so long to reply. In GraphPad Prism, IC50 determination involves fitting a dose-response curve to your experimental data to determine the concentration of a compound that inhibits a particular biological process by 50%. The number of parameters used in the IC50 determination depends on the model you choose to fit your data. Three-parameter model: This model assumes a sigmoidal dose-response curve with three parameters: the bottom plateau (representing the response at infinite inhibitor concentration), the top plateau (representing the response at zero inhibitor concentration), and the IC50 value (the concentration at which the response is halfway between the top and bottom plateaus). This model is simpler and more commonly used when you have limited data points or when the curve doesn't exhibit significant asymmetry. Four-parameter model: This model includes an additional parameter, the slope factor (Hill slope), which allows for asymmetry in the dose-response curve. The slope factor represents the steepness of the curve around the IC50 value. This model is more flexible and suitable for data that show significant asymmetry or curvature. When to use each model: Three-parameter model: Use this model when your data follow a standard sigmoidal dose-response curve without significant asymmetry or curvature. This model is simpler and requires fewer data points for reliable fitting. It's a good choice for initial analysis or when the additional complexity of the four-parameter model isn't justified by the data. Four-parameter model: Choose this model when your data exhibit significant asymmetry, curvature, or when you need a more flexible model to accurately capture the dose-response relationship. The four-parameter model provides a more accurate estimation of the IC50 value when the dose-response curve deviates from a simple sigmoidal shape. In summary, start with the three-parameter model for simplicity and use the four-parameter model when your data require a more flexible and accurate fitting approach.
Hi. How can I compare among three groups ( a-b, a-c, b-c) and show the results on the plot?
Hi. The best option for you is to create a spreadsheet by columns with the a,b and c groups. Then perform a ANOVA with multiple comparisons (compare the mean of each group with the mean of every group), if it's normally distributed, or kruskall-walls if it's not normally distributed. And finally plot it as in this video. But search on channel. There is a video about that.
@@bioinfotips thank you so much!!!! it really helped me a lot!!!
Glad I could help you 😁
you must begin better with the proper data table where the data must be inserted
Thank you for your comment Sebastian. I'll keep that in mind for the next videos 😁

Thank you for making the video. I don't quite get what is measuring after 1:00. What are the orange color labeling? The invasive cells? Which parameter should I use? Count, size, %area, perim?
After minute czcams.com/video/H5cj2wBT59A/video.html, it measures the number of particles (in this case). However, In the spheroid case, you are only interested in the area of the main "particle" which is the spheroid itself. Alternatively just copy the total area in the summary of results window.
thank u for this video king
Glad it was helpful to you nick!
Hi I tried using the same method but I see an error ' no particles were detected. Threshold(255-255) may not be correct
Try to add a threshold adjustment step the particle measurement.
thanks!
Is this open to use? Can I use this in my publication ?
Yes. I believe they have the instructions in the website. If you want you can mention them in the acknowledgments or something like that
@@bioinfotips Thank you for your kind response!
No problem

Hi Nerea, let me check and I'll let you know
Just made this video about it czcams.com/video/TUnu3wNxQmc/video.html
How do you know what pixel distance to set
Setting the scale you mean? You need to take a picture of your cells with a scale bar on it.
I did this. But I have one question, there is a value in row 9 that has no value because the fractional rank was 1. Why does that occur? I have the same problem and now instead of 30 observations, spss works with 29 :(
Hi Bianca. Thank you for your question. Let me check and I'll let you know.
What is the value on that row before the transformation? If there are zero or negative values, these can cause issues during the transformation, resulting in missing values.
The value is positive, same as yours. If you look at your example, the one in the video, you'll see that in row 9, you don't have a number after you did the transformation. I was thinking that maybe it has something to do with the fact that is the highest value of all, but I don't get why the program "deletes" that value.
Oh my bad. I though you were talking about your data. Let me check and I'll let you know.
@@bioinfotips i am curious about this too
how do u determine the cut off value?
Hi. What do you mean?
Cut off value can be calculated bythe highest Youden's index= sensitivity + specificity - 1

Thank you for your request. I'll take a look into it and make a video.
I want to thank you for this nice video. I have a question. What are the units of the data in the analysis table?
Thank you so much! It means a lot. It really depends on the scale you are using but it should be micrometers
Should I set the scale before doing the analysis? Or can I accept it directly as a micrometer?@@bioinfotips
Yes set the scale before doing the analysis.
Thank you so much!@@bioinfotips
I tried this but still data found to non - normal ...sir pls suggest some ways to adreess this problem of skewed data
Hi. Depending on the degree of skewness, I would say square root transformation (for moderate skewness) or log10 transformation (for higher degree of skewness). Let me know if it helped.
I already tried the sqrt and log method ...but still not getting the normality in the data
In that case, why don't you use non parametric analysis?
Sir how to merge AO/PI live and dead cell image & analyse them using Image J? please guide me

Thanks you , but ....One question, when I want to perform the leave test with transformed data following your tutorial, what type of power transformation was performed?
Hi jennifer. What do you mean by "leave test"?
Thanks so much. Your quick informative video saved me a lot of time.
Thank you for your comment. Glad I could help 😃
Thank you, I did the transformation. Unfortunately my data was still skewed!
In that scenario I would recommend other type of normalization according to the type of skewness you have.
Thank you, is there a guide you might recommend that suggests the type of transformation to make?
these are misleading videos. you're not teaching how to analyse anything. merely how to upload software and initialise. title your video properly
