https://crcns.org These are the search results for the query, showing results 301 to 315. https://crcns.org/forum/using-datasets/66445685/954353096 So I have been playing around with the pvc-11 dataset and noticed something unusual when running one of the scripts (script_mean_firing_rates_gratings.m). It produces 3 mat files with struct S.   S(1:12) ought to correspond to the 12 different gratings the monkey was presented with, however, you may notice that:   sum(sum(S(n).trial(k0).counts - S(n).trial(k1).counts)) = 0 For all n, where k0=k1. Which means that the matrices are the same for a given trial, regardless of the input stimulus.    If you change line 55 (of script_mean_firing_rates_gratings.m):                       S(igrat).trial(itrial).spikes(ineuron, : ) = histc(data.EVENTS{ineuron, itrial}, edges);   to:   ...                     S(igrat).trial(itrial).spikes(ineuron, : ) = histc(data.EVENTS{ineuron, igrat, itrial}, edges);     Problem is resolved. Hope this (is accurate and) helps someone who wants to use the processed data. Great dataset either way.

I tried the UNIX commands given in the crcns-hc3-data-description.pdf page 5 and I could reproduce the behaviour for the files ec012ec.187.clu.1 and ec012ec.189.clu.1 used as an example. However, for the dataset ec016.233, I found some inconsistencies. For example: ec016.233$ head -n 1 *".clu.1"; tail -n +2 *".clu.1" | sort -n | uniq -c 4     606 0  231543 1     267 3 So there should be 4 clusters according to the first line, but only 3 unique clusters are present. This also happens in clu.2, clu.3, clu.4, clu.9 and clu.10 of the same dataset. Is there any reason/explanation for this?   Thank you, Ruxandra No publisher rcojocaru 2019-11-27T04:12:43Z Comment https://crcns.org/forum/using-datasets/16979080/775320459 The functions were added to the archive.   Thanks for pointing out that they were missing.   No publisher admin 2009-08-07T22:08:58Z Comment https://crcns.org/forum/using-datasets/16979081/448459530 Greetings,   The .m file containing the natural movie sequence in the pvc-3 data set seems to be wrong. According to the documentation, each frame of the movie is 64x64 pixels, the movie is 6000 frames long, and it is stored as uint8. Thus, the movie should be 64x64x6000x1=24576000 bytes long. But the .m file for the natural movie is 24575859 bytes long.   Cordially, Joaquin No publisher rapela 2009-07-25T03:21:02Z Comment https://crcns.org/forum/using-datasets/16979080/775320458 Hello, The fretrieve_log function calls a couple functions (fload_log, fsearch_log) that are not included in the archive.

You are absolutely right - the discrepancy coming from the fact that the behavioral dataset includes all trials, whereas some are discarded in the electrophysiological recording due to ephys quality control. I will be correcting the behavioral files in the repository soon. Best, Ignacio No publisher isaez 2019-01-24T00:11:13Z Comment https://crcns.org/forum/using-datasets/550563216/460160373 Dear all, Hi, I've got the hc-2 data-set to use raw broadband LFP signals in the Matlab. Also, I've got the scrips but I couldn't have access to raw signals. First of all, when I run m-file it faced with some errors. Furthermore, I couldn't find a way to define the file directory to the m-file. Is there any specific character or something like that for the definition?  I've tried to import the .dat data it isn't working. I've read the PDF files but can't find any helpful thing to solve that. So, how can I access to raw signals in the Matlab?   Please do consider my question.   -Thanks.

Doing so is your responsibility. Various procedures for indexing data points and plotting are described on the MATLAB help website, and are not specific to the reported results.   best, Dr. Johnson No publisher eljohnson 2020-11-30T20:57:10Z Comment https://crcns.org/forum/using-datasets/889853949/851589943 Previously Dmitry Kobak wrote: Can you say in which folder TrialEvents.mat has OdorPokeIn and OdorPokeOut that are "overlapping"? This shouldn't be the case.     Thank you for your explanation. I have realized that "overlapping" does not exist.  At present, I think the variable "OdorPokeIn" means the offset time relative to the time in the variable "TrialStart". Is that right ?   In addtion, I have come up with some new questions.  1. In the data descripition, it says that each single-neuron.mat file contains an array of spike times.  Does it mean sampling times ? 2. What is  the meaning of the name of each single-neuron.mat file? For instance, "Sc1_2.mat", what is the specific meaning for the two number in the file name? 3. What is the unit of the varible "TrialStart"  and how does the value in "TrialStart" match that in "TS" ? 4. Could you explain the meaning of the variables in the "TrialEvents.mat", like "pure-trials" and "BaseStart" ?   I'm looking forward to your explanation. Thanks again anyway for your reply!    No publisher muziriyue 2016-12-30T19:09:46Z Comment
