r-nos_eval在扫描响应中给出错误

Question

[！[在此处输入图像描述][1]][1]我运行以下代码并得到以下错误：

> ev1 <- nops_eval(
+   register = "RegFile.csv",
+   solutions = "output/metainfo.rds",
+   scans = "nops/choiceresults.zip",
+   string_scans ="nops_string/results.zip"
+ )
The following students were not registered or incorrectly filled in their registration numbers:
6
Correct registration number (for 0000000, POMT2_W23_005.png): xxxxxxx
Error in scan(file = file, what = what, sep = sep, quote = quote, dec = dec,  : 
line 7 did not have 6 elements

你知道我该怎么弄清楚是哪个文件产生了错误吗？

扫描看起来干净完整，所有的十字架都可见。

Answer 1

发生此错误时，是由于扫描失败以及Daten.txt或Daten2.txt文件中的数据造成的。您只需要重新扫描相应的文件，然后重新运行nopsscan。

运行扫描时，不要忽略输出中的错误行。这些错误将阻止nops_eval运行。
