You can store data from a CSV file in a pandas DataFrame this way: df = pd.read_csv("data.csv")Īnd iterate over rows, using the first row as keys for each column value, as following: for index, row in df.iterrows(): Seeing what your use case is, I recommend using pandas in order to process your CSV data files. The answer below has been written with this clean CSV dataset in mind. The simplest example being the following: x, y, x1, y1, Probability value Please help.įirst, if you are not comfortable with deep-nested data, you should clean your data in your CSV file (they are not uniform and have duplicates - they are also error-prone if you want rectangles). But by using your code I'm getting output like above. Now based on that value I'm planning to generate the heatmap. I have extracted all the patches of size 256 x 256 from whole slide images and computed "probability values" of each patch. "p" is the probability value of having cancer or not in that particular area. Sample imageover which Heatmap should be generated ]Įxpected Heatmap type ] Any help will be highly appreciated.Ĭontent of CSV file: (x,y) (x, y+y1) (x+x1, y) (x+x1, y+y1) Probability value The details of the probability values (.csv) file format are given below. How can I write a code for heatmap generation using the coordinate points and probability values over an image. I have probability values of some areas and coordinate points. When the new mosfet‘s arrive I will bolt it back together and I can then check for signals etc but would like to be prepared to know what to look for and so on.I have a pathology image of size 1024 x 1360. Does anyone know what the LED’s signify and how many there should be in total ? Updated: I have found this - HCPL0611 Fairchild Optocoupler Ģ) the person who has a look at it, was satisfied that the input stage of the machine is ok and that the LED’s on the board show green. I would be interested to know:-ġ) which component in the photos above is the opto isolator, ( I am not near the machine now to look closely at it) I have ordered 6 new mosfet‘s just so that I know I have good ones. Removing the board there is no obvious signs of burnt out components. I had some one look at it and he spoke to Lincoln who want £3,250 for a new circuit board and mosfets. I still get the HF start spark but no more. I did not use it regularly, but went to use it a few weeks back and it initially worked and then stopped. Hope that someone in need and use this post and I want to special thanks to Bobbesfor helping me. So tig welding was very hard work and ist not similar to soldering Still working on it and now I am learning to make master of TİG welding. I have seen all signals and supply voltages are ok and the machine working good with all functions except trying welding.įinally, replace mosfets with IXFN80N50 and test it for all functions 3 days throughout. I Applied to +15 and -15 volt by lab type power supply to proper connections on board and drive by signal genarator of after UC3854 output circuit between gates of mosfets and fixing easly broken IC HCPL0611 by this way.Īfter replace HCPL0611 with temporarly cheaper mosfets for trying to control all circuits as normal conditions as seen on photo. Externaly drive and test it by oscilloscope. Stay only one way to test this kind of circuits. Because most probably faulty gate circuit is apply positive signal pulsed or DC continuously to mosfets gates and mosfets burn instantly on first second cause mosfets always trying to stay on state. This kind of fault, you can not test gate driver circuits as working normal operation of like on my machine. My first check PFC driver mosfets was broken. On this machine (Invertec V205T AC DC), PFC site mosfets are driving between -5V to +15V PWM signal producing by UC3854 which is fixed frequency PWM IC. I used to IXFN80N50 which is equavelent of APT50M50JVFR. Normally must be installed APT50M50JVFR but someone have used GB75DA120UP IGBT on my machine. First of all, need to a small update for type of MosFets.
