Being my first time handling raw data, I have a bit of a naive question regarding the pfc-2 data set; I'm a bit confused with the format of the clu.# and spikeind. When considering session EE.188, the clu.1-8 files shows a list of indices that varies from 1-46 and the spikeind file a list of indices from 3-77. In fact, in almost every session it seems like there is a unit indexed as '1' with a much higher firing rates than other units. Is there a reason for unit 1 to always have a high firing rate, and why does spikeind not consider units 1 and 2? I apologize if it is obvious or if I misunderstood something.   Thank you in advance for your time!   All the best, Ines No publisher iguerreiro 2022-11-01T10:51:11Z Comment https://crcns.org/forum/using-datasets/632035609/807454877 Dear Jin,    Since the original publications, our group has done the work of getting the coordinates into MATLAB format using the pipeline described in Stolk et al., 2018. You can find these data attached here. Note that there are two repeats between datasets: (1) fcx-2 s5 = fcx-3 s5; (2) fcx-2 s8 = fcx-3 s7. Total n = 15.    best,  Dr. Johnson No publisher eljohnson 2020-10-15T03:00:06Z Comment https://crcns.org/forum/using-datasets/459975262/630072308 Hello all,  first I thank you for the data. Reusable databases are precious for the development of my work. I wonder what is encoded in the files name. For example:   M36_041415_blackbox-cl123115-fix.0spks M36_041415_blackbox-cl123115-fix.P9C1Rm They mean mouse #36, date of experiment 14th of April 2015 was recorded in a black box and then...   cl123115? fix? 0? spks? P9? C1? Rm? Where can I find the spike sorting cluster identification? Thanks in advance.

The data-format pdf (http://crcns.org/files/data/alm-1/Svoboda_lab_data_format_general.pdf) mentions a roiMap struct, but this does not seem to be included with the dataset. Apologies if I've just missed them. Thanks! No publisher swkeemink 2017-04-06T10:50:58Z Comment https://crcns.org/forum/using-datasets/752582760/672793397 I'm working with the HC5 data set, specifically with the data in "..._eeg_1250Hz.mat." I would like to know which layer of the EC or which region of the hippocampus correspond to each shank. After reading through the documentation, I did not see where this information is stored. Is this only available in the hc3 data? Thanks for any help!

I would like to know about the voltage scale of the raw data; what is the unit of the raw data? uV? or mV? I found that number of bits is 16 and voltage range is 8 as well as amplification is 1000. So, the raw data is digital code and it should be converted to analog voltage based on the resolution of 16bit ADC with 8V full scale? And it is the one that is already amplified by 1000? But raw data is expressed as second decimal place, which doesn't seem like ADC LSB codes (it should be integer).   Regards,   Hyunkyu Ouh No publisher hyungineer 2017-08-21T20:22:27Z Comment https://crcns.org/forum/using-datasets/578911566/231943317 Thanks for asking for this information.  In response, the data contributor provided a file containing the semantic labels.  The file is named "attention_categories.txt".  A link to the file has been added to the landing page describing the data set (that is, at the bottom of the About vim-4 page). No publisher jteeters 2023-05-12T23:01:10Z Comment https://crcns.org/forum/using-datasets/984816057/12492180 Dear all,   Thank you for answering the question above, using bz_LoadBinary.m helped us import the data. However, I notice that it only contains 1 column (see figure below). Whereas the data description mentioned there should be multiple electrodes in this file. I have also tried to use a standard MATLAB function to import binary files (>> fread(fileID, Inf, format)), which gives me same shape. I have tried three different recordings from different rats. And they all show the same pattern.   Thus, I was wondering if there might be something with the data or file itself. Does it still contain data from all electrodes, but lost the column indicators? Or is it possible to partition the single column into multiples based on the number of electrodes per rat in the "basename_ChannelAnatomy" file?   Thank you for your help!

I cannot find an accurate information about a brain area of each shank. I can see a file named "MapsSessions.pdf" in a dataset. There are schemes for each animal in this file. I understood that rows are days (experimental sessions) and columns are the electrode shanks. But some shanks are missing! For example, for "Rat 08" animal, shanks 1,2,3 and 4 are missing. For "Rat 09", shanks 17,18.19,20 are missing. And also I cannot find shanks that were in a hippocampus. I can see only a basolateral amygdala (BLA), a basomedial amygdala (BMA), dorsolateral amygdaloid nucleus (LaDL),  a ventral part of basolateral amygdala (BLV), a posterior part of basolateral amygdala(BMP), a posterolateral cortical amygdala (PLCo1) a piriform cortex (Pir), a ventral endopiriform nucleus (VEn), a dorsal endopiriform nucleus (DEn), a caudate putamen (CPu), and two regions that I cannot find in a brain atlas (GP and CeN). But the hippocampus is missing! Then I tried to look at files in "Rat*-Info.tar.gz" archives. But for each animal they have a different structure! For example, for "Rat08" there is a gile named "StructureMapping.ods", and there are a lot of sheets for each recording day. At each sheet I can see the following information: shanks 1-4 are in the hippocampus, shanks 5-12 are from the left amygdala, and shanks 13-20 are from the right amygdala. Such a situation is for any day of Rat08. But this information is in contrary to "MapsSessions.pdf" file! For example, for "20130722" session shanks 5-8 according to "MapsSessions.pdf" are in the piriform cortex, and in the left amygdala according to "StructureMapping.ods". For "Rat09" there is a completely different file named "HistoSheet.ods" with only one worksheet containing a scheme like a scheme from "MapsSessions.pdf". But there is the same problem - a hippocampus is missing and not all shanks are presented. And there is another shank numbering system and it does not comply with a numbering system in data files.
